That is exactly what my mother does, she gets mad at everyone in this house for the most ridiculous reasons. Like this morning, at 11:45, I was talking to myself about how to get to Wave 40 on Monsters' Den: Book of Dread(I'm obsessive about that badge), and she comes and opens the door to her bedroom and says "You know everyone is sleeping!" And slams the door, which was much louder than me talking because it shook the giant window in the living room. Of course, nobody else was even here but me.
