What are things you notice on the first date that will definitely earn them a second date?

It was a long time since I dated but, when my man smiled and laughed and made us others laugh and his scent and sexy body and voice and warm energy and brown eyes , oh those eyes, I knew. I knew I wanted to get closer and closer until we were alone in his apartment where we talked for SIX HOURS - SOBER. And then my date arrived and I dumped him and then the amazing guy with the brown eyes scootched closer to me and I felt like "Oh ok he definitely sees me as more than a friend too, glad we're on the same page"

And he got me to stay the night and I have stayed the night ever since.
