I don't even have any, but I can tell that it's allll case by case.

All I feel is that I saw what I saw, not just from my dad, but from plenty others, and I don't see any problem with having the "toughen up!" mentality....whether it's harmful or neutral.

I think it can be harmful for parents who act like a boy/man should NEVER ever cry...suppressed emotions are never a good thing. And for me, my dad actually never once told me "MAN UP! Stop crying like a little punk!" or anything on that end...I just naturally became that way when I realized that crying in certain situations never lead to anything positive.
