Honk honk!

So, I'm leaving work to go home for lunch today. And, as I'm crossing the street, some guy in his car honks at me and then waves.

I don't know this guy. Never seen him before in my life.

Now, before I rant, let me say that I am aware that I should be flattered and that he just felt like honking...blah, blah, blah.

But...

I just wonder WHAT I'm supposed to do/think when someone honks/hollers/whistles at me (or anyone else, for that matter). What would he have done if I had turned and run toward his car? What would he have done if I flashed him, right there, in the middle of the street? Should I have shouted my phone number to him?

I did none of those things. I just turned when he honked, then continued walking to my car.

I rarely feel flattered when this happens. Mostly, I am annoyed. Because, it NEVER occurs to me to honk at someone, even if the guy was gorgeous and right in front of me. I just don't see the point.

Same reason I get annoyed when cars honk at my friend and I when we're running. We obey the traffic rules and when someone honks, it scares the crap out of us...it doesn't get us all giddy that some idiot thinks we're cute or whatever.

What is the purpose of the honk? I guess I just don't get it... It's not like I got in my car and thought, "Oh boy, I must look super hot today, for that random stranger to honk at me from across the street!!!"
