"All my kids are too smart for their own good. Sometimes I wish they would dummy up."
I heard that and I knew what she meant. It does not mean she wants them to quit talking to her; she simply wishes they would quit talking long enough for her to express her feelings or thoughts on the subject. But, "No-o-o; they know everything."
I have heard the old saw, "When they are young your children walk on your feet. When they are older they walk on your heart."
I don't believe for the most part that they intend to walk on your heart. It is simply a case of being too smart for their own good. And thoughtless.
May all your familial relationships be bright and fulfilling.
