Don't be upset about it, revel in it! The fact that the humans are so stupid that they can't see how stupid they are for being so easy to control by something as simple as purrs and cuteness is a hilarious testimony to their profound stupidity. If they can examine this scenario and come to the conclusion that you're stupid then it is very telling of how deep human stupidity runs. As long as they think you're stupid you win & they lose & are too stupid to catch it. It's actually funny.
