Men do cry.
And why not?
Aren't they human?
Don't they have feelings?
When they see their parents cry in front of them, they cry. 
Although they are meant to be pillars of strength, they cry when their heart breaks.
They carry a lot of responsibilities on their shoulders.
They have their family, yet no one to share their pain with.
Just imagine the amount of pressure they carry but don't express.
They are the best actors, hiding their pain behind their fake smile is their habit.
So please, never ever say men don't cry, because they do!
And there's nothing wrong with it.
