This is very very good, and I can really relate to this, because I move all over everywhere all the time, and mostly lose everyone I was always close to in whatever town I lived in for those 6 months.
I really liked how you wrote this, and I must say I really liked the ending. It's very typical of people to forget old friends and such, even when you thought you'd be friends forever. This just really hit home and I'm certain lots of readers can see themselves in this poem. Great job and good luck!
