Lotta people don't realize when you grow up with people you have an affinity a relationship you don't get with anyone else. After you're twenty years old anyone you meet after that it's different from the people you knew before.
I remember when I was 33 or 34 it was devastating because I realized I wasn't a kid anymore. The great thing about 40 was that I really felt like I had life experience and knew what I was doing now.
