I didn't notice the bag lady in the back of the subway car until I was already seated. That's when the, uh, distinctive scent wafted past.
She didn't want company. The madwoman made that clear, with cursing and yelling and twitching and general unhappiness.
There were about 10 of us in the car. As one, we calmly went out the door - we were still at the station - and moved to the next car.
Not a word was said.
