My sister Klari called me this morning to tell me about her seven-year-old's Halloween costume. His first choice was to be a vampire cow. I told her that a couple of his cousins, the youngest two Weathercolour boys, wanted to be a vampire cat and a vampire wolf (I think) respectively. She wondered if maybe he had been talking to them (my alternative theories include possible exposure to the Bunnicula series or else that vampires in general are so popular in our wider culture that both households have picked up on it and then simply combined it with the general young-person love of being an animal for Halloween). I thought that it was a great idea, but Klari said that she didn't have the resources to pull together a vampire cow costume in the time available. (Mrs. Weathercolour happens to have fake blood at the ready, so it was relatively easy for her.)
Klari offered her son a choice of costumes which were within her power to create. He picked to be a stoplight, just like our mother (his Nana) had years before: black garbage bag with a hole in it for your head, three construction-paper circles, and some tape to hold the circles on will do it. He walked around all day feeling very pleased with his costume, and expressed his happiness by saying numerous times that he was dee-liiigh-ted.
