I won't say weakness in a sense
because strong people cry also, it's part of or emotions that when we are touched, sadden or moved by a situation we cry.
I cry when i read sad books, watch a sad movie, if someone dies etc. It doesn't mean that i am weak because i am a very strong individual but people let out their emotions in different ways.
Crying is good it releases all the pains, joy etc. I think men have a wrong concept about crying is for women. Absoslute Rubbish it's for everyone and it's healthy
