Well, I do write when I'm upset with someone, that's for sure. Recently, I got an email from an acquaintance that told me to please accept an apology for pulling down a posting about an art class. I don't know if he pulled it down, because he doesn't like the teacher, and there is some kind of lawsuit going on between the two parties.
A long time ago, an acquaintance told me, "I'm like Tess, I don't mess."
I think that's a good way to be. Never get into the middle of someone else's mess, unless you are ready to get messy too!
