best friend

i have never been able to hold a friend for longer then a year. something ALWAYS happens to cause us to lose our frienship, they move, i move, they find a "better" friend, we grow apart. it constently changes. and now i am entering my SR. year and i mightbe able to finly hold a friend! yay me my wish has come true, untill another friend calls up and says "i'm comming back!" uhoh this is not good, she moved in grade 10 and my current friend for 1.5 years really does not like her. i have no ideas what i'm going to do. they are both great friends but they just don't get along.
