I consider myself extremely lucky that I have three good friends. And I don't mean "friends", I mean friends. Like the kind that I could call up and say "Yo, I'm in a bind, can I borrow $2,000?", and I'd have it in seconds with no questions asked. The kind that always answer the phone, and are down to help no matter what. None of them are from high school or before.
I have friends that I hang out with more often than that small group, people I talk to on a daily basis and whatnot. The kind of friends where you go "Yo, wanna go grab a beer?", and you hang out. Have plenty of those.
But having a small group that I could count on for anything no matter what, I think I'm very lucky to have.
In the end, there's only one person from high school I still talk to. But even that, is kind of a "Talk to them every couple of months, maybe see them once a year" kind of things.
