Holding a Door
I am never sure how long to wait to hold a door open for a stranger when entering a public place. This happens a lot in the parking garage of my office building. How far behind you is too far to hold the door. I think I hold it longer for older men because they might be a boss or an executive that I might run into again. I guess I wait longer for women too because that is the polite thing to do. If the person is wearing a Red Sox hat I shut the door as quickly as I can and hold it shut while they struggle to get it open.
