Twice in the last week I have run into (ahem) cute, smart, attractive guys with whom I hit it off like gangbusters. With each one, we realized at some point while hanging out that we have had completely tawdry, anonymous sex with each other at some point in the previous year. And each time, I had wished that I had gotten more of a chance to follow up and get to know the fella in question. sometimes, serendipity sends a nice curve ball just when you could use a little cheering up.
