After he left I was trying to complete one of the projects he started and needed the hammer to continue.
I looked in every spot I remembered him working in and a few others I didn't with no luck.
The four year old Zen master (Iris) became interested in what I was doing and I said aloud to myself "If I were grandpa, where would I put the hammer?" Iris then answered "If I were grandpa I wouldn't put the hammer anywhere, I would just relax!"
Later, still looking for the hammer, I asked her again "Iko, where is the hammer?"
She replied "I know!... Its Nowhere!"
Still later. "Iris, have you seen the hammer?" She says: "I don't know where the hammer is so you need to find it yourself."
Wisest of all perhaps though was my wife, who tired of my looking for the hammer which is apparently nowhere, asked the question: "How much is an hour your time worth, and how much does a hammer cost?"
