Most teens I meet these days lack basic social courtesy when dealing with people.

My own son, who basically grew up with his grandmother, the original      guru, has perfect table manners. This is partly because he was      to manners at a very young age. However, when we eat at home, he would not       manners. So I asked him why. He said,” I behave the way I am supposed to         when I’m out, but when I am at home I want to be         .”

That’s when I realized that most parents, myself included, do       their children the proper way to behave outside the home, but they are also         to believe that at home, anything goes.

My       to him was “good behavior has nothing to do with where you are or whom you are with”.

Then he answered, “But I behave       when I’m with others so that they think better of me.” And that is when I realized that I was doing things all         . I explained to him that it had nothing to do with what people think. This         him even more.

So I went on to explain that behavior, whether in your everyday        with people or at the dining table at home, is an         of who you are. Well, at the age of 13, he got it.

So basically, what I am saying is that teaching your children        comes with the underlying lesson that it is not about       to do or not to do, but rather, who they are. This way it is not         ; it comes from within.

Teach your teens or children the      courtesy of greeting their friends’ parents and         themselves when they go to someone’s home. Teach teenage boys to open the door of a car, or any door        that matter, for any girl, whether they are their girlfriends or not. This includes holding elevator doors or letting women step out of the elevator first.

Just         that teenage boys who practice good manners’ and courtesy grow up to become men who respect people in general.
