My boyfriend's sister (who has form for making his problems my problems, if you get what I mean) has just texted me to ask me if I want to do a meal for his birthday at hers. She phrases it like "if you want us to do something at mine...". Its not a big birthday btw.
I did a bit of a double take.
I mean, its her house. Its his birthday. He's her brother.
AIBU to not understand what any of this has got to do with me?
I mean obviously I'll be giving him a gift and a blow job and all that jazz but surely what he wants to do and where and how is up to him? Or her if she wants to host something??
