My First Facebook Drama

I tend to talk too much and that's a problem. About 4 months ago I was mad at someone and posted some snide comment, knowing they'd never see it. This person doesn't have a computer and doesn't even know how Facebook works or anything. I still shouldn't have done it because wouldn't you know that someone told them what I said? I hate it too because it may have hurt their feelings and only caused problems when all it is was a moment of being mad and being snarky. Well, lesson learned. It is the last time I post anything that I don't want the whole world to see.
