I helped my daughter with a school assignment the other day. They were supposed to do a time-line showing past, present and future: a picture of her as a baby, a picture of her now and a picture of what she wants to be in the future. Influenced by my wife's obsession of reading mysteries, my little girl wants to be a detective, ala Sherlock Holmes. So I doctored up a photo of her to include in the project.
She loved it, as did her teacher.
I think she has all the qualities that would make up a fine sleuth: naturally suspicious (believes nothing she hasn't found out for herself), determined to follow through anything she has begun (which also means she can be as stubborn as a mule), and has a rock solid sense of what constitutes right and wrong (which means I'm constantly getting busted.)
