My daughters, who are 30 and 31, made creatures out of milk cartons in preschool. Cute and colorful, with egg-carton eyes. They've lived for more than 25 years on the shelf of my bed. Today, because I am moving to a small, overcrowded house with no (insuffcient) room for me and my stuff, I carried my long-loved creatures out to the trash. And I feel heartbroken.
