Darn, his way is certainly better than what I did when I was a kid. I had a crush back then (like anyone would have).
Everytime we ride the school bus, I always try to find a seat that is ahead of her, but on the parallel side and keeping distance some couple seats away. I would take off my watch and use its face for reflection so that I could see behind me -- which of course looking at her.
Gosh, my I don't know what went around in my head when I was a kid, but I guess that's love to ya.
