From a very early age, my wife and I told our son that there are times and places for everything. I told him, look, when you're in class, you have to be quiet and listen to your teacher, but when you go out to the playground, you can scream and be silly.
The one thing that I appear to have been given, bearing in mind that I am capable of being very, very scatty and extremely lazy, is the ability to concentrate on something I choose to give my time to.
