Kid Ethics

My 3-year-old came to me with a 5 dollar bill.  "I have money!" He exclaimed.

"Is that your sister's money?" I asked.

"It's my money," he chirped happily.

"It can't be your money," I explained.  "You don't have any way of getting money.  You don't have a job."

"I can get money," he rebutted. "I sneak into Sister's room and I take it."
