I met my best friend Crystal when I was 5, and we're still friends 16 years later
We did have a few years where we lost touch, but once we got back together as friends, we were inseparable for a few years! Now she lives in IN, and I live in SC, so we haven't seen each other since the end of 2004. I miss all the good times we had, but we definitely reminisce when we chat.
I'm also still friends with a girl I met when we were 7. We were pretty close until she moved away without a word! Her parents were going through a nasty divorce, so it didnt surprise me she gave no warning on leaving. We too lost touch for a few years, but thanks to myspace and all that, we started talking again a couple years ago. She just got married, and I wish I could have made her wedding but she lived in MO when she got married, and just moved out to WY.
