when I first started going out with my now ex-g/f, neither of us could drive yet, and her mom was taking us to the mall, and We both went towards the same door and I took an extra qucik step to get there before her to open the door for her, and she gave me the worst look and went to the other side saying "ok, I'll go around" and all I wanted to do is open it for her.
She felt bad about it after I explained my intensions, but it's just sad the lack of manners people have today. Luckily for me, my current g/f let's me be a gentleman
It is always fun, though, to see other couples when we go out. It'll be a friday night, we go to a resturant, and I pull the seat out for her and such, and every once in a while I'll hear a "slap" of a girl hitting her b/f on the arm and say "why don't you do that for me!"
