As my children get older, I am often frustrated with RSVPs and parents not picking their children up on time! Accountability is a part of manners. If I invite your child over from 6pm to 10:00am, don't expect me to wait all day for you to claim them! How do we teach our children to be on time when we don't come and get them at the designated time?
I have also noticed that kids will cancel their plans for the next better thing. That was never an option when I was a child and is not acceptable in my home. If you make plans with "friend A", you don't cancel because "friend B" sounds more exciting.
As for the Mr. and Mrs., we allow our children to use Mr. or Mrs. and first name (ex: Mr. Jeff) for friends of our family, but Mr. or Mrs. last name (ex: Mr. Smith) for elderly, teachers, and people we don't know well.
