Commuting in Manhattan

Here are my rules of commuting etiquette. Warning--many of these--in fact all of them--are politically incorrect.

1. Little old people, who are retired, should not, i repeat not, travel on buses and subways during rush hour. People who work deserve to sit. We have no choice about when to travel. We should not be expected--or guilted into--giving a little old person a seat.
   Exceptions--Pregnant woman
2. Women with baby carriages should also not travel during rush hour. They take up valuable aisle real estate, and when their kids are not screaming at the top of their lungs (you can't blame that on the air pressure in the cabin) they are waiting for people to play hide and seek with them. When thwarted, the little brats throw their bottles at the unwilling playmate.
3. People traveling with suitcases--If you can afford to take a trip, you can afford cabfare. Leave some room for the rest of us!
4. People who insist on drinking coffee--I love coffee as much as the next addict. But I don't feel compelled to travel with it. If you can't make it from your house to your office without a fix, check into the nearest rehab.
5. Women who apply make-up on the bus/subway--You are not at the make-up counter at Bloomingdales or in the privacy of your bathroom. I am not fascinated by the fact you can apply mascara on a moving vehicle.
