jack-o-lantern
Every year a form an unhealthy bond with my jack-o-lantern. When I was a kid, I'd spend the whole day planning out my perfect pumpkin face, drawing out various templates until I found the best one. After Halloween, I'd keep my jack-o-lantern in my room for a few days as a doll house of sorts, and then in the backyard to watch it decompose. I still have that strange attachment with every pumpkin every year.
