What if during rush hour you had to dance with whoever you were standing by on the train, no matter how hairy and/or smelly?
Would it result it many, many lawsuits?
Would it result in many new friends? Or enemies?
Would it result in a net improvement or loss in quality of overall dancing?
Perhaps the close proximity would for an improvisation of dance based on close quarters?
Would it make you get a car?
There's never a shortage of rudeness on the subway, and very little kindness. Where does involuntary dancing fall into that scope?
