Thankful I can only be to people who helped me or did me a favor.
There should be an intention to benefit me; sheer random good or bad luck (like your house surviving an earthquake or not) doesn't make me thankful (to what anyway?) at all.
I'd say one of the things I'm grateful for is this great site and the awesome, incredible, intense orgasms I get every time I get when I sign in, check out the posts and pics, have a chance to express my horny thoughts before I can't resist beating off. So then I can get on with the rest of my life and responsibilities and my social life without constantly being distracted by how horny I am - until I really get horny again, and I'm back here to get off agan!
