There is a nesting thing that happens at volleyball tournaments frequented by teenage girls. The girls arrive at the court with huge backpacks or duffle bags. The bag looks like a small holding device, but in reality it is the Mary Poppins carpet bag of volleyball. If you watch these girls you will see them pulling out: sleeping bags, shoes, sweatpants or pajama pants, water bottle, snacks, Nintendo DS, ipods, cell phones, books — the bigger the better…Twilight would be a good choice, and blankets. Seeing these girls pulling all this assorted junk out of their bags makes me thankful that for the most part each girl carries her own bag.
