Lanie has a friend over. It's close to Erin's naptime. I said to Lanie, "I'm going to set the timer for twenty minutes and then it's time for your friend to go home so I can put Erin down for her nap."
Lanie jumps up and down with her hand out like a stop sign, "Wait, wait. How about she goes home when you say it's time for Erin's nap."
"Because it's better that way. It's no fun when the timer wins."
