I stayed in a hotel with my best friend and his girlfriend, but I'm not going to pay my share for the rooms.
You don't plan to pay even though you stayed there too? What kind of problems will that cause?
I'm going to lose some friends for being so irresponsible
Is that really worth it? It is common to pay your fair share when you are doing things like that with your friends.
I don't care if it's common. I don't want to talk about it.
You will have to talk about it when your friends ask you about the bill. Paying your share is the right thing to do since you stayed at the hotel with them. If you don't pay, you basically were using them.
