Read the introduction. I support the purchase of streetlights for our community. My young sons enjoy riding their skateboards in the street in the evening, but darkness makes this a reckless undertaking, even with reflective gear. Further, our family has contributed dues to the neighborhood association for nearly ten years, and no structural improvements have been made during this time. The association has money saved for projects such as these, and it is time to use these funds to promote safety.

What is the author’s purpose?
