An anecdote about her childhood might be relevant, and even charming. The first part of the second sentence provides the topic for this paragraph--imagery in a static scene. The thesis can come before your outline or at the very end of your essay introduction.
Context and background most likely belong in your introduction. Basically, a good introduction provides the reader with a brief overview of your topic and an explanation of your thesis.
Be sure your anecdote is short, to the point, and relevant to your topic. True evidence or proof deserves a body paragraph. The topic for this paragraph should be in the first or second sentence. Do not use lots of details.
The first sentence of this paragraph should include the reverse hook which ties in with the transitional hook at the end of the second paragraph.
