Try not to view it as 'hostile" but "competitive".. I find if I change my wording - it really does help.

Perhaps its more competitive at varsity level as opposed to more of learning the game at lower levels.

I try to think of "expressive" coach's as being very competitive. Easier to prepare for and deal with.

Now when s/he is in my partners or my face ranting we are the worst officiating crew ever - and cheating their team, etc - it went hostile and I got a little hand signal to fix that.

I got one for my loan processor as a joke. But the other day, when I had some first time homebuyers looking glaze-eyed after signing a mountain of documents, I brought in the button from the other office and they felt better.
