Now in case you think, well, it must be you, then...
There were numerous times when, after some discussion, I would say, OK, lets ask the "teacher." This was either in class or at the practica that I went to for years. Invariably, after the usual, here you do it with me, now I'll do it with them "test," I would be left alone and the "helpful suggester" would receive additional instruction.
So, from my perspective, it's going to happen. And the only thing you can do is decide how you are going to react to it.
