People are too busy to notice you. How often have we seen that written here? A lot. Let me tell you a true story:

My wife likes to walk for exercise when she doesn't go to the gym. We were away and she decided to go for a walk and when she came back, she said "You know up there at the end of the parking lot?" I said "Yes." She said "The first time I walked by, there was a man sitting in his car. The second time I walked by he was out of the car, dressed in women's clothes."

So, when we go out dressed as women, people might not notice us. Then again, they might. In fact, they probably will notice us unless we appear to be women doing "women's" things. Standing or walking alone in a deserted parking lot is not something most women would normally do. Think about what you plan to do.

Later, I walked with her and there was a single red sneaker in the vacant parking lot where the crossdresser had been. It's gone this week so maybe he came back and got it.
