How do you know it was "kids"?
Oh,Clyde, I asked that pages ago.
But seriously, star, you sound like the crankiest old-man-in-training I've ever heard of for a 36 year old. I hope you get married and/or have children or find someone to love you and/or a reason to really, really enjoy life soon. It just doesn't sound to me as though you do.
Seriously, buddy, learn to laugh. Ok, I know you're funny [to me at least] but learn to experience joy.
That's one of my great talents. It doesn't make me much money, but it gives me a reason to get out of bed, every single day.
