I'm reading The California Roll by John Vorhaus, and the first sentence is:
The first person I ever scammed was my grandmother, who had Alzheimer's disease and could never remember from one minute to the next whether she'd given me ice cream or not. I'd polish off a bowl, drop it in the sink, walk out, walk back in, ask for another, and get it.Okay, so I threw in a second sentence again, but it really was needed to complete the thought.
Frankly, even without it, I really loved that first sentence. It's just a tad fun while really introducing our main character, a scam artist.
