Me to my 10-yr old son: How was tennis camp today?

He: I had a little problematic opponent this time. He was continuously complaining that I hit the ball too hard from both sides. 
So I told him:
‘Look, you don’t like my forehand, you don’t like my backhand…. but hey, there’s a solution here: ever thought of taking up some other racket-and-ball sports? You might love golf, for example..’

Of course

I am watching my 10-year-old son playing a tennis match. He’s just hit a winning ball, after which I am happily asking him:

Me: ‘Wow, this last ball was great! When you sent your opponent to the far RIGHT corner … how did it come to your mind to hit the ball then to the far LEFT??’

He: ‘There was nobody there.’

..

Of course.

Me and my silly questions.
