I love how threads like these always bring out the hardest hardasses of the hardass internet.
I wonder if anyone believes all that...
Apart from that, I don´t think crying or not crying has that much to do with being strong or not. I know people that never cry, but just get drunk when they are sad, which is pretty much the same thing somehow, just expressed differently.
We all learn not to cry in public if we can with any means help it, and I´m fine with that. Trying to express your emotions to people not interessted in them is out of place, I think.
But if you are alone, or with closest friends it is actually quite a good vent.
