You can only be strong for so long before you eventually find yourself crying.
There's nothing wrong with that...it's what we do.
If you hold in the pain you feel, you're only hurting yourself, so why not cry? or talk about things that bother you?
If we've been given the ability to show emotion, why not show it?
I think it's just silly that people would wear a fake smile and live with all of that pain building up, rather than showing others how they feel, and maybe finding a way to relieve themselves of it.
