I always hate the inevitable interrogations when something gets destroyed, and nobody knows how it happened. But, I imagine the complete opposite would be even more frustrating:
Who broke this?
Me
How?
Ninja moves.
Will you please be more careful?
Probably not
Don’t you even care?
Not really.
Something else I should have added. The side effect of not being able to lie well in his case was also being gullible. He often couldn’t tell when he was being deceived. It helped having practiced and talking openly about it.
