New Backpack

I bought Daynan a new backpack for 1st grade. When I gave it to him I was really talking it up and showing him how neat it was with all it's zippers and compartments and buckles. The wheels in his head were really turning and he'd ask "what's this one for?" so I'd give him a few ideas and then say, "or whatever you want". He took what I said pretty seriously. Hey, maybe his teacher will allow a class pet?!?
