I (20F) organised a day out with my sister (21F). For simplicity I'll call her Anna. We agreed to go for brunch to start with and then do some shopping, get our nails done and maybe finish off with a film if there was anything worth seeing. All was fine and I was really looking forward to spending some time with her.

Jump forward to the day and I arrive at the place first and grab a table. Anna arrives a few mins later but I'm shocked to see she's brought her boyfriend (23M) with her. A little bit of background, Anna tends to only date guys for a couple of months before getting bored with them and she'd only been seeing this guy for about 3 weeks at this point.

I try to hide my surprise and be civil and we order food. When he leaves to go to the toilet, I ask my sister why she's brought him along since we already agreed we're going to be doing typical sisterly things and it doesn't really suit him. She said she didn't want him to feel left out, whatever that means. I said ok, and that I assumed he'd be paying for his own food. She tells me no, it's your turn (we take turns paying whenever we meet up). I was completely shocked that she expected me to pay for his food as well. I think she could tell so she said that she'd cover his order.

Honestly the whole thing really annoyed me and I didn't like the idea of going round stores, trying clothes on etc with this guy following along. So after we paid the bill and were leaving the restaurant I made some excuses and left. Now my sister is messaging me asking what happened and I don't know what to say.

AITA?
