Apparently, we have monsters in our house. These monsters do anything from break the toothbrush holder to drawing on the toilet and bathtub (at least they used a pencil). They also make messes in rooms and spill milk all over the table. Since, I cannot see them, I assume they are invisible or maybe you just have to be three years old before they will reveal themselves to you.

So, any suggestions on teaching the concept of "telling the truth" to an almost four year old?
