Teaching my boys how to respect women the old fashioned way

My pops taught me to always hold the door for a lady, look her in the eye when you shake her hand, and mean it when you apologize. Been trying to pass that along to my boys even though the world's different now. My 10 year old asked why he has to have manners when his friends don't and I told him it's because we hold ourselves to a higher standard. It's about respect and character, not what other people do.
