It Wasn't Me
They have reached the age of deniability. They have realized that they are held accountable for the things that can be proven and what they admit to. Having several siblings to point the finger at is considered an advantage; because you have so many possible suspects. My husband, an only child, has yet to experience the "I didn't do it" when everyone in the room is saying it at the same time.
I am going to miss it when their poker faces become refined. Currently, I am able to tell by the tone of their voices or their facial expressions if they are guilty. If I am able to carry that skill into their teenage years, then I will consider myself very lucky.
