Constant Change

We all change at some point. Some, faster than others. But does good or bad come of it? Both. Today I talked with a friend who I have not spoken to in 3 years. He told me how he changed for the better and that he lost all his friends because of it. If we change for the better, why do we still lose people as friends? I don't think I would want to lose anyone as a friend. Although we head our seperate ways sometimes, or that solid friendship crumbles down into nothing, we shouldn't ignore them. We shouldn't pretend like they no longer exsist. Say hi to them. Smile at them. Because we are only human. We all know how it feels to be betrayed, loved, sad, mad, you name it. So why do we keep ignoring them?
