Okay, so this sounds fake but I swear it’s real.

My brother (34M) and his fiancée (28F) are having a medieval/fantasy-themed wedding. Cool, whatever, I (41M) love them and was totally down to dress up. Until they dropped this bomb on me:

They asked me to be a “horse.”

Not dress as a horse. Not wear a horse mask for a funny photo.

Actually act like a horse.

Their plan: They wanted me and another groomsman to wear these realistic horse costumes — one in front, one in back — and “gallop” them (the bride and groom) into the reception on a fake chariot. Like, neighing, hoof sounds, full commitment.

I laughed because I thought they were joking. They weren’t. They even showed me videos of horse movement tutorials and sent “practice schedules.”

I politely declined. I said I’m happy to wear a costume, help decorate, even do a funny skit — but I’m not willing to be a literal horse.

They LOST it. My brother called me selfish and said I was “ruining their dream.” His fiancée texted me a long message about how “true love requires true sacrifice.”

Now half my family is mad at me, and the other half thinks it’s hilarious. My mom says I should just “suck it up for one day,” but honestly? I’m a grown man. I’m not prancing into a wedding on all fours while neighing like a Clydesdale.

AITAH?
