While I've always believed in the equality of women, old-school Hippie that I am (actually, I expect the equality of women, which can be a bit troublesome in these days of political correctness), I usually do things like hold doors, offer to carry stuff, pay for meals and so on. But then, I generally help whoever needs help at any given time. I suppose the most chivalrous things I've done are: 1) Promoted the equality of women for the last 40+ years, 2) decried gender stereotypes for an equal span and 3) worked in Women's Health for 22 years.
