Politeness

Okay, so today after practice my mother dropped me off at 7-11 to get some milk and a lady was following behind me. I wanted to be polite and hold the door open for me, and guess what I got some four minute lecture on how she doesn't need a man to hold open a door for her and blah blah blah. At that point I wanted to just slam the door in her face, I was just trying to be polite! I wasn't implying that women are feeble and weak, I was just being nice. I really don't want to get garbage, for trying to be polite it's just messed up.
