Stickers are an odd thing.
In childhood, they hold a strange power over us. They are a great reward, something to strive for on a chart, or something that can make us smile after a scraped knee has been bandaged up. And you betcha, we can't have enough of the damn things. Plaster everything in them, please. The more, the merrier.
But in adulthood, they are maddening. And when you have kiddos... they are EVERYWHERE.
