I remeber when I would move in and out of my dorm during breaks and at the end and beginning of the school year and I would be carrying loads of boxes and bags and I can't tell you how many guys would rush pass me only to get in before me and slam only to let the door slam in my face -- I hate that!
I absolutely love it when a man opens the door for me or I see him do it for another woman...I always give tell them "thank you" --- usually they seem surprised to hear that...
