person A: I've known my best friend since I was 4 years old.  He joined the Air Force after high school and moved out of state and I was really upset when he left.
person B: Oh it's always sad when someone you care about leaves. Can you at least keep in contact with him?
person A: Oh yeah_comma_ we still keep in contact over the Internet daily and visit each other every few years.  But I miss when we used to hang out every day.
person B: I know. It is hard to say goodbye to people but he is doing a wonderful thing at least.
