Thre's still a lot of stereotyping in our society about men and feelings. Frankly it's time we just stood up and collectivly booted it out the window. I've got feelings, we all do, and it's time to quit pretending that hiding that proves much of anything. I never was a stereotypical male (despite being an admitted armchair sports nut) and I've never really approved of the male stereotype that says bury your feelings. It accomplishes nothing as far as I'm concerned, but since enough of them cling to it, that makes it hard to get rid of.
I've never considered hiding feelings a sign of real strength and I doubt I ever will.
If a Master truly was cold and unfeeling, my question would be why are you serving him? You deserve better (whomever you are).
