Hmmm, I guess there was the whole meeting the parents thing for most people, which would set up the habit of picking someone up. I never experienced that. My own parents would have expected me to be capable of sizing people up without their help. And all through high school I was in a relationship with someone I had known since we were kids, so I didn't date until I was well into adulthood.
But most of the dates I've had in my life were of the dating cold variety. They were my opportunity to get to know the person; I seldom did that beforehand.
