Train up a child in the way he should go: and when he is old, he will not depart from it.
Proverbs 22:6 (KJV)

We must be doing something right! Check out this recent conversation with my 7 year old daughter:

“I accidentally lied to Mrs. L today so I sat out 5 minutes in recess.”

“You lied to Mrs. L?!”

“Accidentally! I didn't mean to. I thought she was asking me if somebody else was talking, but she was asking me if I was talking and I accidentally lied.”

“So, you had to sit out in recess for lying?”

“No. Mrs. L didn't know I lied. I just knew I lied. But it was an accident.”

“I don't understand. Why did you sit out in recess?”

“Mom, I made myself sit out because I lied!”

“So does Mrs. L know you lied?”

“No.”

“Did she see you sit out at recess?”

“Yes.”

“Did she ask you why you were sitting out?”

“No. She doesn't care.”

“So why did you sit out?”

“Because I lied!”
