Close Friends<br>I once had a really close friend that I went to school with. We always looked out for each other. One day he moved off to school. I was sad that we would not see each other. Fortunately, I was able to buy a phone so we could talk everyday.
They think their friendship is good.
They were sad they couldn't see them.
