Yes. I hate it when people tap the mat instead of me, or if they tap really light. If I can't feel or hear their tap, then any pain is their responsibility as far as I'm concerned; however, I still feel terrible about hurting them. If I tap too light or late, then it is my own fault for both getting into the situation and tapping in the wrong way. So I hardly ever blame my mate. In fact, the only time I get angry at my partners is if they do something illegal like insanely hard punching/elbowing (weighted whether we are doing regular or "light punching" grappling), eye/orffice gourging, putting your fingers where they don't belong, or doing a submission with the intent to break bones/joints (like really really fast and hard kneebars, armbars, or heel hooks).
