S.B.
All I know is that from the time my son was very little, he opened doors for me and his sister and let us in or out first. His teachers have commented on him opening doors for women at school. They're like, "What kid does this these days?"
Hello! That would be mine. My son, now 15, gets out of the car and opens my door for me. It's not because I'm lazy, but I want him to have manners and be a gentleman. It started with me, but he's carried it out and will continue to do so. He was invited to a very upscale business dinner with some of my colleagues and he held the door for the women and entered last. He did not eat until everyone else had their plates and began to eat. And, his napkin was folded on his lap as I taught him when he was little. He knows the difference between a salad fork and a dinner fork, a soup spoon and a tea spoon. I got so many compliments on what a refined young man he is.
I have tried opening doors for plenty of elderly gentleman and they wouldn't allow it. They held the door for me and allowed me to enter first.
It's just manners.
Some people have them and some people don't. None of my son's friends open doors for anybody. It's everyone for themselves.
If my son is with me, I never open doors and if he's not, I open a door and go in first if the man behind me doesn't have a clue. I won't slam a door on anyone, but I'm not going to stand there and hold the door for a man. Like I said, elderly gentleman, I will, especially if they have a cane or a walker or something. Strangely enough, they don't let little things like that stop them from being chivalrous.
Chivalry isn't dead. It does seem to be getting phased out however.
Mothers have to teach their sons manners from the time they are young, just as little girls need to know their manners as well.
That's just my opinion.
