While the Cat's Away, the Mice Will Work!

One evening, last week, I was pleased and excited to leave the house completely unassisted by shortish people. The husband character that lives at my house with me agreeable amicably to keep all three short people who also reside in our home with him, in the yard, whilst he worked.
I was gone for a blissful 3 hours. I was quite amazed and delighted to find the said husband had managed to put up a wall while supervising short people of the ages of 1, 4, and 6.
