Yes I do occasionally get angry with him. Not nearly as much as I used to now that I have set rules to follow and know what's expected of me though.
I do express it at times. It really depends on what I'm really angry about. Did he really do something to make me angry or am I just angry with myself for being an idiot? Sometimes when feelings of anger creep up on me I need to take a few moments to reflect on what's really bothering me. However, if I am upset with Master for something I let him know. He can usually tell before I have a chance to mention though as I have a tendency to pout. LOL
Typically he'll ask me what's wrong, I'll hem and haw about it and finally tell him and in telling him realize that it was silly and had nothing to be angry about to began with. And if he feels he was wrong, yes he will apologize. A real man can do that with no problem, it just might not happen as quickly as we'd like, but it does happen.
I no longer scream and holler and have temper tantrums as I did in the past. Knowing my place helped fix that right up. Plus knowing that I can get spanked for being a brat is a good deterrent for acting up.Unless of course, I'm in the mood for a good ass whooping, in which case I could just as easily ask for one.
