"You shouldn't lie Teddy," Remus said to the four year old on his lap.
"Why?"
"Because it's not nice and only little, rotten boys lie. You're not little and rotten are you?," Remus asked and Teddy shook his head, "Good. Now go apologize to your mother."
"Do grownups lie Dad?" Teddy asked instead.
Remus paused, "uhh..."
"So? What'd you tell him?" Tonks asked several hours later.
Remus sighed and looked down guiltily at the floor.
"I lied and told him no."
