Lost friend

Facebook and other online communities are quite amazing.  I can't count how many people I have found through it that I wouldn't have normally even thought about.  Today I found one of my best friends from back in the day when we were in 3rd and 4th grade.  We used to carpool with each other back we went to school together so we got used to being with each other a lot almost like brothers would.  I had a chat with him tonight over facebook and couldn't believe that I had found one of my good friends from long ago and at the same time had no idea what to say to someone that I knew that well.  I really want to meet him again but I am somewhat weary about how I'll feel about my long lost friend after 8 years of no contact.  My first impressions based on photos and and what he's spoke about with me makes me think that we've both changed very much from when we were friends.  I hope we can meet soon and find that we're both still great friends... I'm just not sure if that will come to be or not.
