Man Rules:Crying
1. Crying is Blackmail.
Use it as you would black mail. Do not over use it. Realize you are using it, even when you don't think you are using it.
"Tears of Joy" is an oxymoron. Crying is an appropriate response to pain. Serious Pain, like when someone close to you dies, a limb is severed or you got shot. Pain.
Anything else is a plot to make those around you feel guilty to get what you want.
According to the Wikipedia:
In many cultures, crying is associated with babies and children. Some cultures consider crying to be undignified and infantile, casting aspersion on those who cry publicly. In most cultures, it is more socially acceptable for women to cry in public than men.An insincere display of grief or dishonest remorse is called crocodile tears, from the ancient anecdote that crocodiles would pretend to weep while luring or devouring their prey.
Try as you might tears will never be really understood as anything else. You might get tolerance, possibly sympathy. Anything beyond that, the black mail worked. Claim your prize and stop crying.
Corollary:
It has been said (by women) that crying is equally socially unacceptable as cursing, slamming doors or throwing things in anger (see Dammit Tool). The social grievance might be equal, but the verbal and physical violence to inanimate things is an admission of guilt. It does not demand things of others. Crying creates guilt in others or thrust it upon them. Therefore is black mail, not simply a release of emotion.
