I've been married and completely out of the game for 20 years. I appear to be in my early 30's according to most (and that's cool that people say or think that), but I'm actually 40. I'm not the old guy just looking for sex, I want to hang out and have fun too. How can I know when a girl I'm talking to (more specifically a waitress that's obviously at least 10 years younger than me) isn't just being nice to the older guy? or how can I determine attraction without becoming the old weird perve?
