The Buddy Box

The Twins formula arrived in a big, sturdy, box. Dad recalled all of the fun he had with boxes as a kid and thought throwing it away was a waste. So he taped up the sharp edges (would not want paper cuts you know) and let the kids have at it.

Mom noted that it was filthy on the outside. 

When they are old enough, Dad will encourage them to make boxes into clubhouses, cars, planes, and spaceships by painting, coloring, and cutting out windows.
