It’s strange how the most justifiable things in life need no justification.
No one ever thought it necessary to explain the heart-stopping joy of holding her first child for the first time. No one ever bothered to justify himself for enjoying the smell of a fragrant flower. No one ever took the time to wonder why she thought bright, spring days were magnificent.
All of these things are so obviously good and right that there is no further explanation needed. That simple fact is the reason every mother can tell when her child is lying. It’s only when little William starts trying to explain why he tripped Henry, instead of just saying he did it, that there is cause for real concern. It means, quite plainly, that he did something he knew to be wrong, and is now in the throes of a futile effort to convince his mother why it was actually an accident, or quite the right thing to do given the circumstances.
