“Well, no, I don’t think so. There might be a bus.”
“Oh,” Sally says, slouching back into her more
characteristic slump. She pulls her long legs—in the
prefaded jeans that cost more than the rent on my
first apartment—up to her chin and plugs in her
iPod. “Great. A bus.” I may as well have suggested
she take a coach and four. Good thing. The last
thing I want is Sally running off to the city.
