A tiny deer with a giant chocolate cupcake. Together. With me. All the time.
I had a tiny plastic fawn that I carried with me everywhere when I was in kindergarten. It was so small, it was in constant danger of being lost, so I got some string – about four feet of it – and made a leash. That turned out to be impractical, since elementary school hallways are non-optimal walking grounds for tiny wildlife. The leash snagged on things. No one understood the love of a girl for her pet. So I took to wrapping the leash around the fawn and returning her to the safety of my pocket. Since she was no longer tiny, wrapped in four feet of string, she had become much less losable. Problem solved.
If you need your own security fawn, you can get a picture of the deer + cupcake, among other things, from Elizabeth Soule here.
