Do you know that person who doesn't know when to just shut up? The one who insults you without even trying? The total buffoon in social situations?
I am that person.
Yesterday, I ran into some people I knew (of) in high school. I think I said some things that were complete insults to them, but I didn't mean to. I didn't even realize it until today. Now I wish I could go back and not even tell them that I may (or may not) have known them.
So if you meet someone who doesn't know when to shut their mouth, it might be me.
