Am I the asshole??

25

AITA for dropping my sister's kids at the child free wedding that she was at?

To make a long story short, I (f25) am a medical student. My free time is very limited and I have lots and lots of commitments. My sister (f33) has 3 kids all under 10 and she often expects me to babysit for her which isn't the main problem, but she drops them off at random times with very short notice or no notice at all!.

The other day, She called saying she was on her way to drop the kids off at my place, because she was attending her friend's child-free wedding and she couldn't take the kids with her. I had a huge argument with her on the phone because I had to study for my upcoming exam but next thing I knew, the kids were at my doorstop and she was already back in the car and then drove off with her husband.

I was so pissed I couldn't handle it. I decided to get dressed 30 mins later and take the kids right where their mom and dad were. I drove them to the wedding which was at her friend's house and had them go in. The men there tried to stop the kids til my sister and her husband came rushing. My sister was shocked. She started shouting after me but I quickly got into the car and drove off.

I went home and she started calling me. After she realized I wasn't going to pick up, she sent few texts calling me unhinged and a "fucking b*^$" for putting her in this situation and embarrassing her infront of her friends. She mentioned that by bringing the kids to the child free wedding I disrespected her friend which affected their relationship amd caused her and her husband to go home and miss out on tje rest of the wedding. Her husband called later and I picked up thinking he'd speak to me rationally like he always does but he scolded me saying that it wouldn't hurt if I kept the kids for few hours, and then expressed how disappointed he was and how selfish and petty I was to do this to my sister and her kids.

Now I'm thinking I should've sucked it up for few hours. AITA?
