I have 7 grandchildren and 11 great grandchildren. It is quite easy to tell the homes that teach manners and consideration and the ones that do not. There is certainly a difference in the stress level depending on what family is visiting. We have one family that we entertain in the park due to the behavior of the great grandchildren. It is so sad because when they have children, those children will be the same way or even worse. I feel like an old fuddy duddy sometimes because I can barely hold my tongue when they are mis-behaving.
