I Never Seen A Man Cry

Why is it easier for a man to open up to a woman? I've been thinking a lot about this subject and came up with an answer: Women have that nurturing nature that endears people to them so even the toughest of men will open up. Let a man show weakness in front of other men and it's like "What you crying for, man up, real men don't cry or show emotion, etc." I understand that men were raised to be tough & strong and I can respect that. A young man coming up, he's never seen his father shed tears or show any emotion so he grows up thinking being emotional is for the birds. It's understood that it's acceptable for a man to show emotion under the following circumstances: Loss Of A Loved One, walking his daughter down the aisle on her wedding day, seeing his baby born for the first time, etc. I feel like this, I'm one of the strongest men around so it would take A LOT for me to break down. A man holding it in is like a septic tank, keeping emotions/feelings bottled up creates a strong odor that can become unbearable.
