What you are basically saying is that they can observe you knowing your shit plenty of times, but they don't actually put a little checkbox in their head next to "this dude know what they are talking about" until you yell at them and say "I have demonstrated plenty of times that I know my shit, and you need to put that checkbox in your head" ?
Actually I was pissed at them for something else. I think the act of chastising was what changed our interactions, not the content of said chastization.
