Ding Dong, Tick tock

After I put the kids to bed last night, JT was just coming in the door and went back there to say good night to the kids. As he said good night, Sophia starts bobbing her head back and forth frantically, saying "Ding dong, tick tock, ding dong, tick tock, ding dong, tick tock" JT tells her to stop and go to bed. In response, she just stares at him and says "Ding dong, tick tock." JT, again, more seriously tells her to stop and go to sleep. She, more quietly, almost desperately looking at him with pleading eyes, lightly bobs her head back and forth and quietly says, "Ding dong, tick, tock." JT says Sophia what are you doing, go to sleep. She defeatedly responds, "Just laugh and I'll stop." He replies dryly, "Ha, Ha." She happily responds, "Thank you, good night!"
