I think crying is vastly underrated, and something western society - especially men (Big boys don't cry ...) is ashamed of, to its detriment.
I was a Samaritan for three years, and i have lost count of the number of men and women I have either heard crying down the phone, or crying in front of me, and without exception, they always apologised, because I am supposed to be embarassed. My response was always the same - "Don't be sorry, there's no need, it doesn;t embarass me, and it's good for you, let it all out ..." and with that 'permission' people would do just that.
So don't worry about showing your emotions, it is a good emotional release, and it shows you care, and may break the ice for otherreulctant criers around you. We are far too buttoned up about our emotions, time it changed.
