Henry and Walter wanted me to go downstairs to get all of the splash balls that they dropped down the staircase.  Henry assured me that they wouldn't continue to drop the balls down there.
I crouched down and told both boys to put their eyes on me.  They did.
"If I go get them, will you drop them downstairs again?"  I asked.
"No," said Henry.
"Yes," said Walter.
Henry and I continued to eye Walter, who very likely intended to drop the balls back downstairs.
"No," said Walter.
I eyed him.
"Are you sure?" I ask.
"No," he replied.
