So can we talk about what a horrible person I am?

I have absolutely no filter on my mouth and no matter how much trouble this has gotten me into in the past, I never learn. And I'm not talking cursing. Sometimes I simply don't think before I speak and I end up looking like a complete asshole.

Exhibit A: I'm in 7th grade and my friend's horse has just died. She has only owned the horse for a month tops. In an effort to comfort her, our friends are all spouting out words of condolence. Suddenly it's my turn and I say "or maybe you should have gotten a horse that wouldn't die". We weren't friends much longer.

Exhibit B: I'm in 12th grade and living with Rich and June (my stepfather and his mother) while I finish the school year. I am all about my independence and June is all about being the nurturing ever present grandma. During a car ride she turns to me and says "I'm going to miss taking care of you" (I was moving out in a few months). Again, not thinking I reply, "well it's not like you take care of me now." While I didn't see the harm in my response, Rich flipped out and nearly kicked me out of the house. It took an hour long conversation (during which I retold the horse story) and me apologizing 5,000 times for him to calm down.

And there's today... I'm honestly surprised she didn't slap me.
