See?

This is why I don't do relationships. They're hard to manage, they're hard to handle, it's hard to keep the partner pleased and happy. Especially when I don't even know what I'm saying is hurting them until it escalates out of control. Some things I know that I say will hurt, but others, when I'm just trying to have fun and thinking the other is having fun, I have no idea that I'm hurting the other.

I'm joking.
It's not really true.
I didn't mean to hurt you this time.

I'm sorry.
