Did you know that I accidentally pissed off a friend?
What did you do to upset them?
I thought that my thoughts were normal, stupid me.
Sometimes people are just a little bit sensitive. You should try to watch what you say around them.
I just didn't think the stuff that I said was offensive.
You just need to know your audience, and not say things around your friends that could hurt them. It's not a big deal if you apologize.
