Is this a good topic?

<p>The essay prompt is "what's that sound?". I thought I could have a unique take on it by starting off with the sound of our doorbell when the little girl next door comes over to play. Then I could go into more detail about her, her rough family life, and how my spending time to her has given me a new perspective on community service. My only concern is that the essay focuses too much on her instead of me. Thoughts??? And if anyone wants to, I can PM them my rough draft so you get an idea of what I'm working with.
Much appreciated :)</p>
