What was the most gentlemanly thing you've ever done?

I'm a bit short of gentlemanly experiences, but here's one that might bear recounting, just for the final line.

It was a blazing hot day and I stopped to offer two elderly ladies a lift. One refused, the other saw Mrs Didge in the car and accepted. So they got in. I went out of my way to drop them where they were going (no  big deal) and as they got out one of them said, "Thank you very much. I'll do the same for somebody else."

I thought it was a good example of "what goes around, comes around." Nice lady.

I grew one long hair on my chest (from all the coffee I drank as a kid)....... Then plucked it.

We will never speak of this moment again........

I'm a lady, but good manners are for everyone.  I often stand at the door, holding it open for all to enter or exit.

Of course, I hold my hand out for tips....

I will not include the many times I have held a door, chair, helped put on jacket, held my coat over in the rain, and offered my coat to my wife, because I feel this SHOULD be expected.

I have done many of these things for strangers, but I once witnessed a man with a full pick-up truck accidently dump all the lumber in the middle of the road during a torrential down poor . . . I jumped out and spent 15 minutes re-loading the entire pickup truck with the lumber and climbed back into my car feeling like I had swam a couple miles . . .

I have also stopped on a couple of occasions to jump start a car, and to help change a tire.

Gentlemanly (of a man):  Befitting a gentleman; chivalrous, courteous, or honorable.

Someone who worked in the same building I did was there when I was explaining what I had done with a personal item of a customer that I had found.

She was in close proximity to the conversation and volunteered that the customer could rely on what I had just said because I "was an honorable man."

People usually don't form such an opinion based on a single incident.

I try to be "gentlemanly,"

Perhaps I am succeeding in general.

Ooooo.  I always cringe at gender specific behaviors and labels.  I would prefer to see anyone being thoughtful and courteous .. Male or female.
