There was probably a ten year period in the 100,000 year history of humans where young swains jumped out of the car, ran around and opened the door for their date.
But we are less human because boys don’t do that anymore.
That should be on the list, too. For a while, I dated a man who did just that - opened the car door for me. He also strictly adhered to numbers 3, 5, 6, 8, and 9 on the list. He seemed to be such a gentleman, but eventually I found out that he didn't believe in #10. ;-) So much for being a gentleman. I'm a church-going woman, so ended the dating.
I think I should show my sons the whole list for when they start dating.
