Mr. and Mrs. Still Sounds Right

I always taught our three sons to address our friends by Mr. and Mrs. The title shows respect and good manners. Is this old fashioned or is it still proper to do?

I feel it is one way to teach our children respect in a world where children, as well as teens, are failing to be taught respect for authority, teachers, and adults. By addressing an adult with Mr. or Mrs. the title puts just the right distance between a child and adult. I think it is a big mistake for children to call their teachers by their first names. Yes, there are schools that promote familiarity and "we're all equal" feeling but the teacher is the authority in the classroom and should be held in high regard and addressed properly.

As a grown woman I still wouldn't think of calling my parents friends by their first name. I was taught respect at a young age and because of that, my parents knew their teachings would last a lifetime.

What do you think?
