Call me old fashioned, but I can't believe some of the manners, or shall I say, lack there of, I see when out and about at the stores, restaurants etc. What ever happen to taking your hat off at the dinner table? You don't know how many times I see kids and teens chewing gum like a cow, not to mention chewing their food with their mouth open and talking with food in their mouths. I taught these things to my child, and they are teaching theirs the same. If we walk in front of someone at the grocery store (while they are looking on the shelf) we say, "excuse me". To the cashier we say, "have a good day/weekend". When ordering at a restaurant, when asked our order, it's, "a diet coke, please".
My youngest are now teens. When we go out, they now noticce how many people don't use manners. Do you teach your kids these things? What other manners are important to you?
