Alter Egos

From the text:

"Well," she said, "I'm seventeen and I'm crazy. My uncle says the two always go together. When people ask your age, he said, always say seventeen and insane.

"It's just, I love to watch people too much, I guess."

"Bet I know something else you don't. There's dew on the grass in the morning."

Laughter blew across the moon-coloured lawn from the house of Clarisse and her father and mother and the uncle who smiled so quietly and so earnestly. Above all, their laughter was relaxed and hearty and not forced in any way, coming from the house that was so brightly lit this late at night while all the other houses were kept to themselves in darkness.
