My mom does the same thing all the time.. My dad's done it too, though. I could be talking to them about something completely different, they'll yell at me about getting a job (I'm trying, okay?) or something else then say that I brought it up. Sigh... Sometimes I wonder if they don't just enjoy hearing themselves scream and yell.
