We understand it from the old Bogart and Eastwood and Wayne films.

The gentler sex is frail of mind and does not understand things quickly outside their sphere of knowledge. It goes back to our pre history where physical body structure evolution slowes and our mental evolution began. men were hunters and women were gatherers. Men needed to be more aware to find things and therefore we pick up on little things quicker and "roll with it" as it were, like greetings. whereas women have evolved to be more focused on things to understand that they got the right plants and not poison, making things they don't know or understand right away as foreign to them, its as though you were greeting them in swahili.

This is of course not true for every woman, but a "majority" which falls suit with why most women don't understand the head bow.

Good sir, I would like to point your attention to a philosophy of mine; "shit happens" that is all.

what an intriguing proposition sir! I must say, I rather do agree with you.

What it comes to is a simple gesture of respect. A nod says to fellow, "I see you and respect your space." A return nod says, "Thank you for acknowledging me and respecting my space. I do the same for you, dear sir." A passing nod to a gentleman is seen as respectful. Mind you, a gentleman's actions are what make a gentleman.

Without being melodramatic, I suppose this nod may be a sort of salute shared by gentlemen from the days of old. I wonder if it has continued uninterrupted from centuries back or if it has merely been revived by young men of our era.

probably seems too much like you're checking them out but super obviously
