Anyone who has ever had small children--or been around small children--is very aware of the box phenomenon. This is the way it works. You spend a zillion dollars on your kids for Christmas/birthday/holiday of your choice. Then you spend another fortune on paper, ribbons, gift bags and cards.
The event finally arrives and the kids rip the paper from the gifts with wild abandon and accompanying shrieks of joy. Now days most toys are wrapped in so much plastic, twist ties, and other crap that the kid will have to wait three more days while Mom and Dad work their way through the packaging.
In the meantime, the kid is sitting in the corner playing with the boxes. Why?
Because boxes can be anything. They can be a fort. Or a dollhouse. Or a pretend stove/refrigerator/sink. They make a fine play car or truck or plane. Do you need a table? Yep, turn that sucker upside down and you have a great table. One of my kids tucked all the flaps inside and spent many happy hours "watching TV".
If you have a cat or dog, the box is a wonderful bed or cage. For that matter, if the box is big enough it can be a fine bed for the kid. When the child is all done playing the box becomes great storage to hold all those toys. Eventually, Mom and Dad liberate the "real" toys from the packaging and the boxes are stacked in the corner until trash day.
That's when the final irony is revealed.
The boxes will last longer than the toys. By trash day, the toys make the trip to the curb while the boxes endure. Seems like it would be easier to just buy some boxes.
