A catcher who moves the mitt into the strike zone after receiving the pitch has just told me that she didn't think that pitch was a strike. I have no problem with that, as I probably agree with her. However, the danger happens when I see a really close pitch that I am convinced just may be a strike, and then I see that mitt move. That is when the catcher influences me, and once again, I will agree with her that the pitch was indeed a ball.
