Silence of the Tank

Whenever the Tank sings be it a Wiggles tune or U2, Caden gets very agitated. He whines and acts like it's hurting him. Seriously. This morning the two of them were playing a Raffi CD but when the Tank started in on the chorus, Caden not only told him to stop but he also signed the word "stop" just to make sure he came across clearly. The Tank looked crushed, asking "What's so bad about my singing?". It's really starting to give him a complex because though I cannot sing in tune whatsoever, Caden has no problem with my crooning. Now we have a new form of discipline out of it. Whenever Caden balks at something we can threaten "You better finish your peas or Daddy's gonna start singing!"
