How do you know if you really know someone?
I remember asking myself this question a lot as a kid. As I grew up and developed relationships with people, and cut relationships with people I've found that I never really got to know someone until I've seen them express different emotions.
In order to get to know someone, in my humble opinion, you've got to see them upset. You have got to see them mad, glad, sad and every color of the rainbow. You don't truly get to know someone until you have seen them shout, cry, and laugh till it hurts.
It's in how you react, that truly defines who you are! (or want to be..)
