What do you think of me snitching on my friend due to the fact that she had sex in our friends small studio apartment?
Why do you want to snitch on her for having sex in your friend's apartment?
I think our friend should know about it.
I don't think it's a good idea to snitch on your friend for having sex in your other friend's apartment. If no one and nothing got hurt, then snitching on her just seems petty. I think you should keep that information to yourself.
I'm mean. I hate her. I just want to cause her trouble.
If you want to just cause her trouble then you definitely shouldn't do it. You need to move on and pretend this didn't happen, because at the end of the day no one got hurt.
