foot in mouth
This is going into my biography as the MOST ridiculous chain of events I have ever been part of. It couldn't have been more perfect if it had been scripted for a movie.

Scene One: Me and my grandmother riding home from church on Sunday.
Me: "So, did you hear that [brother] is engaged."
Her: "WHAT. Oh, no I didn't. When did that happen?"
"Um, well, I heard Tuesday, maybe Wednesday."
"I have told your father before that I don't really like that girl. She's not perfect. No one's perfect enough for your brother."
"Well, hmm. I'll be sure to be careful when I get engaged, make sure that he's perfect."
(Segue quickly into new topic.)
"So, are you going to [cousin's] graduation? When is it?"
"I don't know, I haven't been invited yet, it's coming up very soon though."
(As Grandmother drops me off)
"Well, I'm sorry you couldn't come to dinner with your father and and mother and I, but I'll see you next Sunday."
"Yes." (runs away to feel bad.)

Scene two: Today
Close up shot of text message from brother's girlfriend/fiance "Thanks for Telling Mom and Dad"

Realization: A) My parents didn't know my brother was engaged.
B) My grandmother told them at lunch on Sunday
C) I told my grandmother
D) I am a catalyst of destruction

ARGH.
