Well I'm no stranger to dating... So most of the common sense advice above is pretty much as I'd expected.
However, it's nerves that get me. If it's someone I like then sitting there playing it cool isn't an option then my nerves get shot to peices and I sit and babble.
Last time I went on a date with someone I really liked I scared the crap out of myself on a mountain bike for a couple of hours beforehand, just to work on the fear factor. However, if it's someone I don't know or they're obviously interested in me I can sit there, cool as a cucumber and seem to find the right things to say.
Does anyone else experience this phenomena?
