My dad was a stickler for manners. We used to go to the old Capitol Court in Milwaukee, a place where all the department stores had "double doors." It was always my 'job' to get ahead of the adults (my parents or a stranger) and get the doors opened. If I didn't get to be johnny-on-the-spot, I heard about it. To this day I open doors, and oddly, our favorite place in the mall has the same 'double doors.'
