I think I am going to eat my boyfriends chocolate bar.
why do you want to eat his chocolate bar?
He was being a jerk lately
I understand you're not pleased with your bf's behavior but it's rude to eat his food without his permission. You better ask him before otherwise the situation will escalate over this silly thing.
I'll ask him when I'm done eating the chocolate bars.
It is rude to eat someone else's food without asking. If you really want some chocolate you can buy some at the store. They might be very angry if they find out about it.
