Toilet Paper

Recently Sam put his bed up against his closet so that it can't be opened. I think he gets scared of it at night. We don't store many clothes in there, it's mostly winter wear and some bags and shoes that don't fit.  I was trying to purge some clothing that no longer fit and pass it on, so I made him move it so I could access the closet. The first thing I saw when I opened it was what appeared to be two entire rolls of toilet paper piled in closet.
"WHAT is this?" I demanded.
"Toilet paper," Sam replied. (I still ask the stupidest questions, I should have learned by now).
"Okay, WHY is there an entire roll of toilet paper unraveled in your closet?" I asked.
"No, two," Sam told me.
"Two what?"
"Rolls of toilet paper, mom," he said.
Deep breath. "Okay, Sam. Why are there two rolls of toilet paper unraveled in your closet?"
"Because Viv toilet papered my room."

Then we had a conversation about wasting toilet paper, that went no where because Vivian wasn't around.
