Today my dad was angry because I tied a twist tie instead of twisting it. I told him to "settle down". That made him go berserk.
Perhaps I should have told him to "calm down" instead of "settle down", but still, holy shit.
We aren't on speaking terms after that, not for a few days at least. I'm not even going to respond to his moronic questions anymore, in fact, when I'm around him I'm going to be wearing ear plugs from now on.
