Yesterday as I waited on an elevated platform for my Manhattan-bound train, a woman in her 30s walked by and I noticed that there was an obvious outline of what may have been something like Johnson's baby powder that was showing on her backside through jet black pants. Knowing how people can be unpredictable, I thought about whether I should mention this to her. I waited for another woman to arrive so that this could be brought up to her by someone of the same gender, but that did not happen. She was nicely dressed and I figured she would appreciate the ability to use her hand or tissues to swipe or pat down the area, and avoid this residue being seen by others once the train arrived. I walked over to where she stood and said, "Please excuse me, I do not want to be thought of in the wrong way, but I want to let you know that there is an outline of white powder appearing on the back of your pants that needs to be brushed away." She glared at me as if I insisted on the exclusive right to do the brushing and replied as follows: "Don't you have anything else to look at this early in the morning?" I could not let that go unanswered and said, "If you are even suggesting that I am here at this hour to check out women's rear ends, you have problems far greater than what is currently on your pants. You are perfectly free to do as you please ... sorry to have mentioned it at all." Then I moved away and about two minutes later from a farther distance noticed her doing exactly what needed to be done to rid herself of just about all remnants of the powder. Next time I may keep things to myself even if I notice anything similar on another person. Figuring out people can be a near mission impossible at times.
