You, are a true lady.
My mother would have beaten me senseless if she ever caught me doing something like this. So, in this day of age, I still do these things because it's part of my character. Plus, it allows me to see what a real woman is on occasion.
My father would have beaten me senseless if I refused to yield a bus or subway seat to a lady. I always keep in mind that if my father knew that I failed to surrender that seat, I would be left unable to use it anyways....;-)
