Tristan Quote

I forgot to mention what Tristan said when we were in line for security to get on the plane.
"You have to take off your shoes now so they can check them." I said.
"Why?" asked Tristan.
"They just need to make sure they are okay." I answered.
There was a pause of several minutes and then I heard poor little Tristan ask me-
"What happens if your shoes are not okay?"
