You explained things to Chad, even going online to show him that this was widespread, and that people in clown costumes had been attacked and hurt.
Chad argued with you. He remained unhappy even when you gave back his share of the money. You pointed out that the costume was really too big for him now, so he could save it for next year. You helped him come up with other ideas. Finally, he seemed to settle down, the two of you came up with a fairly simple, but fun 'pumpkinhead' costume for him (that would be better for the hot weather you're having), and you relaxed.
Today is Halloween. You're setting everything up, when you hear a loud thud from Chad's room. You go back there to find he's pried the screen off his window and is handing his clown costume out to his best friend, David.
Is Chad still going trick-or-treating? Will he be going as a firefly? Do you need to call David's parents?
