People who are inclined to walk all over other people will do so -- or attempt to do so -- regardless. I wouldn't want my surgeon to be crying in sympathy while he was trying to remove my brain tumor, but I would not find it strange if my boss cried while telling us our coworker passed away suddenly. So it's when and why you cry that matters, not that you cry. Crying is a normal behavior for human beings, but it can be taken to excess. I will say this, and you can pass this along to your father: my father never showing any emotion except annoyance at me led me to believe my father didn't love me. I still think that.
