Should I say anything to a friend that's ditched me?

Well, as they say, "friends will come and go." Some people think this true only for the duration of school. However, I think the big friendship tester is what happens once you're outside of school. If I'm correct, most people tend to move on and not keep in touch so much. Then everyone starts going out with new people and doing their own thing, and I think that's where it ends. If you're not still super tight out of high school, it may not have been as strong a friendship as you first thought. If a friend is only there for you in school, you may have been a form of social entertainment for each other, but no so much friends. My thoughts on this are to let it die. Time for some new and probably better friends. For the both of you.
