I decided to have fun and party with them
Why did you decide to party with them?
They were so willing to have a good time with me, I can't afford to let them down.
It is good to party every now and then to relax a bit. Just make sure to not over do it.
I'm going to have fun, just don't tell me what to do.
Sometimes fun ends up being too much fun. All I am saying is monitor yourself so you do not go overboard.
