I'd like to say something like: "Let's talk. If we like each other, let's meet. If we have a nice time, let's do it again. And if we are really lucky, we can keep on doing that until we come up with even better ideas."
Of course, you probably want some details, stats, conversational topics, historical data. If so, just ask. I'm happy to tell you whatever you would like to know.
I posted a bunch of pictures that my cousin took of me playing with the neighborhood kids one Halloween night. I feel that they convey who I am better than I could possible express in words.
By the way, if your ad says "isn't seeking a relationship or any kind of commitment", I will not reply to you. I have no idea why you are on this site, but I'm not interested in whatever you are selling.
