This. Except I'm not limited to authority figures and that's sometimes very hard to handle. Like if a friend wants to invite me on monday but I already have something planned with another friend that same day I sometimes feel like giving the real reason would make them jealous. Yes, I know I shouldn't do this, and I'm working on it, but it's not easy. It's especially hard when the real reason is something like "spending time with you in particular is very stressful for me and I can't handle it".
