Holidays and family meals rarely go as smoothly as people hope. Between following traditions, preparing meals, and inviting everyone, Thanksgiving can turn into a test of patience more than anything else. When one family member makes a sudden change to their diet, it can push that tension even further, especially when everyone’s been planning the meal for weeks.
This happened when a woman uninvited her younger sister, as she couldn’t accommodate her vegan requirements 2 days before the occasion. The elder sister posted online asking the community if what she did was fair.
The story

A 26-year-old culinary student shared on Reddit that she was hosting Thanksgiving this year and wanted to make a classic meal: turkey, mashed potatoes, and the usual sides. Her younger sister, who recently became vegan, called two days before the dinner to ask if everything would be vegan. When told it wouldn’t be, she got upset. The host said some dishes were already vegan, like green beans and berry pie, and told her sister she could bring her own food if she wanted to.
Instead, the sister messaged other family members privately, asking them to make their dishes vegan too, and told them the host had requested it. The host found out after an aunt texted her to ask whether honey was allowed in the rolls. When she realized her sister had misrepresented her instructions, she told her not to come.
The reactions
Many readers of the post sided with the host, arguing that her sister crossed a line by lying to the rest of the family. One person said, “Forget the vegan stuff, your sister decided to lie to the entire family to get her way, putting words in your mouth. That alone is very much not-okay”. Another user added, “Sis isn’t as concerned about being a vegan as she is about getting her way. Honestly, I wouldn’t feel guilty, as she LIED to everyone.”

Most readers said that the sister should not have gone behind and lied about the host, and broken her trust. Many said that even if the sister wanted more vegan options, the way she went about it was unfair to her sister, who had been planning the dinner for a long time.
Several people were also surprised by the younger sister’s demands made only two days before the dinner. One said, “Who waits until two days before a meal to make sure everything is vegan to cater to one person? One person’s diet shouldn’t dictate the entire menu, unless they are hosting, and even then, you’d need to accommodate people with other allergies. Plus, a fair number of vegan substitutes hit other allergens like gluten and nuts.”

Many people start planning their Thanksgiving meal days before the dinner, such as buying ingredients in advance, and some even prepare some dishes ahead of time. Requesting to change the entire menu just two days before Thanksgiving means wasting all the food and money. Also, even if the menu changes, not everyone can eat all the ingredients due to medical restrictions.
Another person who follows a vegetarian diet called her sister’s behavior totally unfair, “I’m a vegetarian, I don’t expect my family to serve entirely vegetarian meals, and that’s far easier than vegan. As long as there is enough to call a meal, or a warning to bring food, I’m fine.”
Most families handle food differences like this by making sure there is at least something for everyone, and if not, bring your own. Nobody should expect to ask the host to change the entire menu because of their diet, whether it’s a family member or someone else.
One user summed this up by saying, “I don’t understand how people on special diets demand everyone eat what they eat. I’m on a diet, so do I get to dictate that everyone eat only salad? No, that’s not the way it works. Bring your own food to complement the vegan dishes that may be there, or eat at home and visit after dinner.”
Everyone has their own preferences, but expecting a whole family to follow one person’s diet isn’t realistic. If you know there won’t be much for you to eat, the easy fix is to bring something for yourself. That way, you still get to be part of the dinner without putting pressure on anyone else. Most families would think that’s fair.
Others criticized how the sister handled the situation after the initial disagreement, “She can bring a PB&J if she has to, for all anyone should care - being a vegan is HER preference, not a medical necessity like gluten-free, and she shouldn’t expect everyone to accommodate her on a day meant for everyone’s enjoyment. She went behind your back to try to change things, and that was a bit much.”

Many agreed that being vegan by choice doesn’t mean the same as having allergies or medical conditions. Other people can have allergies to gluten or something else that can pose health risks.
One commenter compared it to how they handle their own food limitations: “I have an allergy to a common spice (not anaphylactic but still unpleasant), and I don’t even ask people to change their recipes. I just ask that they let me know so I don’t eat their dish.”
That’s a really balanced way to handle it. You can always ask what’s in a dish or check ingredients ahead of time; most people are happy to tell you. It keeps everyone comfortable without putting the host in an awkward spot.

Being an adult means understanding that other people have their own routines, tastes, and limits. Trying to control a family dinner and getting upset over something that could have been avoided ruins it for everyone.
Simple ways to keep the peace at holiday dinners

A few small things can keep a holiday dinner from turning into another argument.
- Mention your needs early. If you have specific food needs, mention them as early as possible. Last-minute requests can stress everyone out. If your request cannot be accommodated, try to find an alternative instead of making it a big deal.
- Bring your own food. No one minds if you show up with a dish you can eat; it saves trouble for everyone.
- Don’t rewrite the menu. You can suggest, but you don’t get to control. The host has already done the work.
- Appreciate the effort. Even if you skip half the dishes, thank the person who made them. Hosting is a lot of work, especially around this time of the year.
- Keep it off the table. Holidays aren’t the time for debates about diets or lifestyle choices. Eat what you can, skip what you can’t, and move on.
The takeaway
Thanksgiving never really goes the way you plan. Something always burns, someone gets annoyed, and someone brings up the wrong topic. But if everyone can enjoy the food, appreciate each other, and focus on making memories, that’s already a win.
