One poignant instance illustrates this perfectly. My daughter wanted me to buy her candy but had not behaved well enough to warrant an extra treat.

“Mom,” my daughter said, “people without money need help, and people with money need to help them.”

“Yes, that’s right,” I said.

“Well, I don’t have money, and you do, so you need to help me and buy this.”

A perfectly well-reasoned, thought-out argument.
