Attending a last-minute party can be stressful enough without having to worry about an unexpected allergic reaction.

So when one house guest brought her own safe wine to her family’s party to avoid triggering her allergies, her sister-in-law somehow decided it was an insult to her hosting abilities.

Read on for the full story.

AITA for bringing my own wine to a house party

I (F39 now, 32 at the time) was invited last minute to my then sister-in-law’s house.

They were having a catered murder mystery party, and one of the couples had canceled, so they invited my now ex and me to fill the spot.

She wanted to attend the party, but she knew she had some complications that not everyone has to deal with.

I have a lot of food allergies and knew the caterers couldn’t have known since I was a last-minute addition. My sister-in-law was also well aware of my allergies.

Regardless, she tried her best to make the most out of the situation.

I ate before we went, in case I couldn’t bring any food, and I brought two bottles of a safe wine.

When we arrived, I greeted everyone and quietly handed the wine to the caterers, explaining that I had allergies and could only drink from those two bottles.

At first, it seemed like everything would get off without a hitch.

The night progressed, and we had a great time.

But she soon learned that her behavior raised some eyebrows.

A couple of days later, I heard from my ex that my sister-in-law was upset that I had brought my own wine. She said it was embarrassing, that I humiliated her in front of everyone, and that it was disrespectful to the caterers.

This left her confused, as she was only doing what she thought was best.

I don’t think I was the AH. I just wanted to have a good time like everyone else without getting sick—but maybe it’s some social rule I don’t understand.

She followed every polite step possible, yet somehow she still managed to catch the blame.

What did Reddit think?

This entire evening was built on shaky ground from the start.

This commenter thought this house guest only did the best she could to meet her health needs.

Food allergies can be very serious, and not everyone understands that.

This house guest already did way more than her due diligence.

Her sister-in-law may have walked away embarrassed, but ultimately, that wasn’t her problem.

She deserved to have fun at the party like everyone else.
