Mayhaps your study is over, but I just saw this thread. XD
I think the terms "gentleman" and "lady" are outdated in our society. With those terms, I feel as though some characteristics are old fashioned, but other parts encompassed in such a term are worth passing down.
When I think of "gentleman" I think of a guy who is classy, respectful, formal, and overall has good manners, especially in regards to women. When I think of "lady" I think of a girl who is classy as well, more passive and submissive, not crude, polite/good manners, things like that.
But in today's day and age, I personally think that a majority of people don't fall under those categories, or at least the notion of the gentleman and lady has changed a little, in that a lady doesn't have to necessarily be passive or regal, but she can still be respectful, good mannered, and polite. Likewise, gentlemen don't have to necessarily wear top hats, speak with extreme formality etc., though they still would do things such as be chivalrous, have good manners, be respectful, etc. The terms gentleman and lady also carry a connotation of being something that often brings up the imagery of fancy rich people, but nowadays, anybody can really be a gentleman or a lady.
Just my two cents. And yeah, I agree with Miha; Monopoly man in his tophat and massive handlebar moustache = epitome of the gentleman!
