After arriving home from work, I found out that Courtnay, our six- year-old daughter, had written on the washroom wall at school. I talked to Courtnay about the importance of respecting others and their property. Then I asked her how it was discovered that she'd written on the wall.
"I don't know, Dad," she said.
After reading her a bedtime story that night, I asked again if she had any idea how the teacher had known for sure who had written on the wall.
"I don't know, Dad," Cournay again replied.
Then I asked what she'd written.
"My name," she said.
