It's classy. Very polite and thoughtful.

I can't remember a period in my life when I didn't do that. It's just a courtesy.

I always do, don't really know if I like to or not but that is how I was raised

I hold the door open for the elderly, like the ones with walkers and such.

I hold doors open for anyone

It is basic manners and polite behavior. I was raised not only for women but for elderly and handicapped as well. I will also hold for men if it is convenient and helps move everything along. I am never one to be rude and just cut anyone off. At least not intentionally.

I open doors for people regardless of sex. Now if I'm in a relationship with someone I try to do it more often for her.

Not really no

indifferent

No, that's sexist.

Chivalry never dies in my books :)
