Liam's Tail

Currently, my life is a myriad of poopy diapers, endless feedings and toddler temper tantrums that seem to only happen at crucial napping moments; however it is also full of snuggles and giggles. The following is one such giggle.
Liam has recently taken an interest in Rocco's tail, and ignoring my requests for him to stop. Yesterday, I noticed that he was about to grab it, so I said to him "Liam, don't pull Rocco's tail, you wouldn't like it if he pulled your tail." Upon hearing this he got a perplexed look on his face and slowly looked back to see if he did indeed have a tail. I then asked him, "Where is your tail?", thinking he might spin around to look. Instead he pulled out his pull up, pointed down and said, "There!"
