Chivalry

I was walking into science center today and as I approached the door a guy that I know, but who generally seems to be kinda rude to me opened the door and allowed me to enter the building before him. I was slightly puzzled seeing how we generally enter the building around the same time every day and not one other time has he held open the door. Once I walked into the building I realized that there was a tour to perspective students being given a few feet behind us. There were also 3 other hanover male students and 2 female students heading toward the same door we entered. This made me come to the conclusion that the only reason he held the door open for me was to look good in front of the touring families and other students.

It made me think about how much chivarly and the meaning of chivalry has changed. It seems like two or three generations ago people actually did things for women out of respect thoughtfulness. Now a days (not it all cases) it seems that men perform these acts of chivalry to make themselves look better. And maybe even more manly to other men and bystanders. Do you guys think that chivalry has changed in this way? Do you think that some/many men perform these acts only to benefit themselves instead of doing them to show respect for women?
