The Teacher is convinced that Netflix is run by malevolent ghouls who delight in sending something she can't wait to see by way of Paris, Alaska, and Timbuktu. She is determined not to be vanquished by ghouls, and so she has a plan.
She hordes Netflix envelopes. She does this by sending back two disks in one envelope. Every time one of the ghouls routes a disk through L.A. or Chicago, she throws away the envelope it came in and sends it back in one from her horde. And cackles.
So far she's stockpiled forty-three envelopes. I'm getting worried.
