"Do you remember when you were little and you were always worried that gravity would cease to exist?" I asked Big Kid.
"No, not really."
"I think you were in first grade. Black holes and no gravity were things you thought about a lot."
"How would no gravity be a bad thing? It sounds awesome," my 8-year-old asked.
"It would be complete chaos. You'd probably float into the atmosphere and die," Big Kid explained.
"But have you ever imagined hula girls in zero gravity?" he asked.
There was a moment of silence while we all considered that.
"...No, little kid, I haven't. Why would I?" I asked.
"Why wouldn't you is the real question, " he replied.
