Quick personal rant: my dad scolds me for a lot of things, and proceeds to tell me about how I'm as useless as my mother. Just now he got me to plug in another laptop in my room, and did the previous sentence about 3 times. He even smacked me for not understanding his vague instructions, and insisted he was 100% clear (and when he isn't, he'll say "there're some things I can't describe, you should know better", not helpful when trying to follow someone else's instructions to a T).
