For tw0 years, I never thought twice about driving my neighbor’s daughter t0 school.

Vanessa and I never created any official arrangement.

Sophie lived four houses away.

One morning, while I was packing Emma’s lunch, Vanessa knocked on my door.

“Would you mind taking Sophie today? My Pilates class got moved and I’m already late.”

“Sure,” I said. “We’re heading there anyway.”

The next morning, she asked again.

Then again a few days later.

Eventually, nobody asked anymore.
