When I get on the subway elevator I like to pretend I’m the elevator police. I think to myself, “Lady with a double stroller, ok go ahead. Slightly overweight guy in a business suit not carrying anything except a frappuchino, let’s move it along to the stairs there buddy. Homeless guy carrying all his possessions in two overfilled Duane Reade bags, come on in. Crazy yelling lady with only one bag, let me check the weight of that. Even crazies need exercise.”
