" Esperanza’s sexual preference flip-flopped like a politician in a nonelection year. Currently she seemed to be on a man kick, but Myron guessed that was one of the advantages of bisexuality: love everyone. Myron had no problem with it. In high school he had dated almost exclusively bisexual girls—he’d mention sex, the girls would say “bye.” Okay, old joke, but the point remained. "
