" Just then he noticed that Amy had that look, as though she wanted the street to buckle and split so she could fall right in. Dan saw the cool crowd from her school hanging at a table in the front. So that was why she didn't want to go in. Evan Tolliver was at the head of the table. Dan sighed. Even, the human supercomputer, was Amy's dream crush. Whenever Evan was near, she got her stutter back.
"Oh, excuse me, I didn't notice Luke Skywalker," Dan said. "Or is it Darth Vader?"
"Shhh," Amy said. Her cheeks were red. "He's coming."
"You mean Evan Tolliver himself is about to set his foot on the sidewalk? Did you bring the rose petals?"
"Cut it out, dweeb!" Amy said fiercely.
"Hi, Amy," Evan said from behind her.
Amy's color went from summer rose to summer tomato. She shot Dan a look that told him he was in serious trouble.
"Hey, Evan," he said. "I'm Amy's little brother, Dweeb. Nice to meet you, man. "
