Sometimes or they act like they don't understand and you're the bad guy when you treat them like they treated you all along. It was no big deal while they were doing it (because "that's just how they are" or "they were just trying to make so and so happy"), but you're just mean when give them they same treatment that they have given you the entire time you've known them!
