Friendships. They either last a life time or not very long. They sometimes last a while. But I don't think mane people relive how valuable they really are. Like one day they wake up and be like, "wow, I really care and treasure my friendship with so and so." but most likely that same person will realize this each day.
Friendship is a beautiful thing. It should be cherished, and cared for. Because one day you may become enemies with that person or God forbid, that person dies and you never see them again. But there is also the chance and again God forbid that you die. And they never see you again.
I really strongly advise you to remind that person or a group of people you really care about them, and remind that you care about them. Because our lives on this wonderful and amazing planet are not long.
And before you know it, it will all be gone. And I'm not being harsh that is how life is. Life is harsh, even to famous people. It does not matter who you are, how old you are, how much money you have, how ugly or how pretty you are you have your time then its gone and your dead. Nothing matters. Because once your in that grave your there and you can't come back.
So let the people you leave behind remember the fun and good things about you. Accomplish the good and not the bad.
I have lost a few friends from a stupid argument, or because they changed, or because they couldn't except me for me. Then there is always the fact they moved or died. And it is painful. Because you know you where part of that stupid problem and you didn't stop it...
