Know your Friends. And yes, there is a reason why i wrote Friends with "F" and not with a "f".
And do not be mad if someone let you down...in the end we are all just people. We decide who can get into our heart, if they hurt us, it's our fault. Kinda. So Know your Friends. And be careful who you let in. It is your...our responsibility. Oh, but do not live in fear of getting hurt or don't even think on closing yourself creating big walls around you...so you think you are safe. It doesn't work that way, and believe me, it's better to take a chance and get hurt...than to never feel the warmth of a friendly hug.
In time those walls will become a prison. If you wanna find good friends you have to risk your heart and prepare to get hurt =\ it's kinda like Loving another person...well...it's really almost the same principle...
Be careful but don't forget to live...and try really hard to know your Friends.
Right know i'm going to visit some old Friends, those special ones...that you feel they live inside your head...when you talk to them you are more honest to them than if you were talking to yourself.
