My grandson is 8 years old, plays sports, is a very active young man. He is sometimes very clumsy, spilling one glass of beverage after another because he doesn't look at where he's putting it down to assess whether it's a good place or not. This drives his mother crazy, which, of course, is cause for much nagging and "to do". Can I tell her that he's not doing it to make her nuts, that he's just 8 years old?
