How we cite our quotes:
"All you need is your eyes and one other person. I pick somebody on the street, the mall, a store, wherever, and I follow them. Say it's a her. I follow her for fifteen minutes, not a minute more. I time myself. The game is, after fifteen minutes of watching her, I have to guess what kind of card she needs" (21.27).
See, Stargirl's not nosy. She's just observant. And very empathetic. She uses her powers of observation to connect to those around her through random (and some not so random) acts of kindness.
