"Thought we only used numbnuts here."
When our sons did something wrong, my dh used to refer to them as "numbnuts." Unfortunately, one of our sons began using that term at school when visiting with his friends. One day the teacher said to him, "You know, that really isn't a nice term to call someone." My poor son had heard it so much he'd turned it into a form of endearment.
As for all those PPs I've been LOL about, I don't think there have been any mentioned that are missing from my collection. However, I think the spoiled, unruly children top my list. Half of my grandchildren fell into this category - especially the oldest and the youngest group. The inbetween groups had more sense. When asked for advice, I've told both sets of parents that what their children really needed was parents who parent, not pals.
Lastly, but not least, I cannot abide people who tailgate. It is an extremely dangerous practice and causes horrendous accidents.
