Absolutely! And there's a lot to that bumper stick that I see which essentially says that everyone is happy when mama is happy. In my house, it kinda goes like this. If you want life to go pleasantly, humor your mother. Otherwise, she can make things miserable for you. Even when you're legally an adult. I'm reasonable and I listen and I can be persuaded to change my mind, so it does work both ways. But then there are times when life is sooo much easier when she just sighs and does what I ask.
Even after my daughter went off to college I still insisted on certain safety rules when she was home. It caused a huff, but then it's my house, my car, my rules......LOL....I remember those 'huffs'!!!
