I think that I might leave two girls at a restaurant.
Could you tell me why you want to leave them behind?
They were friends of my previous girlfriend, they don't deserve my company.
It's not right to just leave people behind at a restaurant. You should be more respectful of people and their time.
I am not feeling well, and I don't like them so I think that is a good reason to leave.
If you don't care about them then that means you shouldn't spend time with them anymore, but since you already went out with them this time, you should be a good person and take them home.
