It happens all the time. You’re walking down East Avenue and see this kid heading off to class. He looks normal. Nice kid. But did you ever think that maybe, just maybe, his backpack is filled with spiders?
You know as much about the number of arachnids in his backpack as anyone else. That number could be zero, but who knows, it might be ten thousand! That’s eighty thousand little legs crawling around in there. Maybe. All we’re saying is, it’s possible.
Think about it, it would be unreasonable to just assume someone’s backpack has no spiders in it whatsoever. So it’s just as unreasonable to assume their backpack is filled with books instead of considering the possibility that it’s bursting at the seams with tarantulas and black widows and stuff.
And what would be holding him back? There’s no law against keeping a big bag of spiders on your person at all times. Someone out there has to be doing it. Maybe it’s this kid. Who else could it be but him?
At the end of the day, there’s only one true way to find out that someone’s backpack isn’t filled with spiders: punch their backpack, and if thousands of tiny spider voices cry out in pain, you know you were right all along.
