I agree a whole lot. I've taught my kids and we teach my grandkids to say thank you. They wouldn't think of getting up from the dinning room table without saying thank you for the meal. I told them it doesn't matter if you didn't like it but if someone makes the effort thank them. At work people get on the elevator and just say what floor, like it's your job. They don't say please or thank you nothing. I was in a bad mood one day and someone was being rude the way she barked out her floor # and I said Please, thank you very much and she just looked at me like it was a foreign language. Manners can make a difference in someone's day; even if you don't know them. I smile at everyone.
