Just got home from a date and I wonder...

I wonder... It was a third date. I kissed him after he walked me to the car. and no "ooh!" no socks rolling up and down. When we talked I wondered what he was passionate about (granted I didn't think of asking that straight out until later, I had asked what he enjoys doing for fun). He seems great and caring and intelligent, but not really opinionated or excited. Maybe it is because he still seems a bit nervous around me, but I don't know. If I'd felt something during the kiss it would have helped. But nothin'. arrgh...
