Friends?

Two post in one day! What? I just had stuff on my mind. I was looking through my fb friend's and found a whole bunch of people I was once so close to that I no longer ever hear from. I also have a friend that won't accept my request that I once considered my best friend. Why is it that life separates us like that? I also wonder if the people from my past know how much they have meant to me. People enter our lives and change us. Good or bad they leave their mark. Why is it so hard to tell people how you feel? Maybe it's just me. I have typed a name in the message box so many times and deleted the message without sending it. Love is the one thing in this world we can give for free. Why is it that we are so stingy with it?
