My experience wasn't that smooth and I doubt this will be seen, but why not? This was with my first girlfriend before we dated. So we're in the theater and watching the trailers. No idea what movie it was for, but the guy in it said "Are you nervous?" to someone so I grab her hand in mine and repeat the line, emphasis on the "you." She loved it and we held hands throughout the whole movie. Was kind of a big deal for me, at the time.
