Input: Hello again AITA, you guys have previously weighed in on the long running battle between me and my sister so I figured I'd turn to you again to see if I really messed up. I'm always on my family's bad side so I appreciated the neutral input last time.

Somehow it's become a tradition in my family that one family member host a Friday night dinner once a month. Last night was my night. My oldest sister and I have not been speaking since our vacation (click on user name to see why if you're curious) and I was able to avoid her at the January and February dinner at other's houses. I really, really didn't want her in my apartment. So I decided since she hates spicy food and her kids are allegedly allergic to peanuts, I could side step the  issue and make this Thai peanut noodle dish that I love. I announced it well in advance in the group email what I was planning. 

Well since my sister is much more diabolical than I give her credit for, she had her husband drive the 2 hours to my place, feign that she didn't know I was making something that allowed her to say "you know my family can't eat! Isn't the point of a family dinner so all the family can enjoy!" While clutching her pearls (literally). Then my niece claimed she could feel the "peanut residue in the air" and it was affecting her ability to breathe. So my sister dramatically took her to the emergency room where all turned out to be fine.

But again, I lost. My sister played me like a fiddle and the entire family took her side. Dinner was ruined and I'm the bad guy. Again. I honestly just tried to side step the issue of having her around but making somthing she and her kids couldn't eat--and announcing it well in advance.

My family thinks I'm the asshole. Am I the asshole?
