I've made great friends along the way, but there's something comforting about the familiarity of friends you've known for your entire life. Well, maybe not your entire life yet, but at least from when you were in school.
Sometimes you drift apart. It happens. Life gets in the way. Distance does make a difference. Time takes its toll.
But then you somehow get into contact again, and it feels like you've never left. Besides, they know your deepest darkest secrets and your most annoying quirks but still talk to you anyway. Who else does that?
