On the first day of High School, which means that we are all 12 or 13, the attractive girls, took the attractive boys by one hand, leading them to where there was a cushy rug, and they formed a back rub circle in the corner of the classroom. It was day one, no classes, and the blondest of them, no, she wasn't dumb, that was just the colour of her hair, I cried when she cut it, said some rot about how a human being needs 7 hugs a day to function... I'm sure that the other 20 kids on my side of the red line, uninvited to their PG rated orgy thought that they were all a pack of assholes who should play in traffic too, but golly were they nice to look at... (Years later, one of them dressed expertly as Wonder Woman for Prom. Oh. I never thanked her for that. Where are my manners?).
Fortunately for Adam, you need at least three people to make a back rub train, or any other sort of human train.
