I know everything you said, and there is only one thing that could be thought of as even remotely offensive. Now, you either are right, and someone can't handle the truth, or you're wrong, and you're entitled to be wrong once in a while. Either way, you are taking this way out of proportion. I said things that night to people a thousand times more cutting and didn't offend any of my friends. The point is that if someone gets offended, they never were a friend to begin with. Can't please all the people all the time. Take it easy on yourself.
I offend lots of people without trying. It's something about the way I talk, my tone of voice, the way my face looks; the latter two I was obviously born with and can't help. The point is, it happens. I hope you come back soon.
