Based on physical appearance, Andrew and Joel were identical. Their tall, lanky frames were topped with a shock of thick, black hair. Their
dark eyes seemed to take in everything at a glance, and their crooked grins put everyone at ease. Despite looking like twins, they were polar
opposites when it came to their interests. Andrew was an avid athlete-a football and basketball star-who never walked when he could run and
never sat down when he could stand. He loved rock climbing, swimming, and surfing. Anything that kept his body in perpetual motion appealed to
him. Joel, on the other hand, preferred cerebral activities. After school, he often could be found participating in a lively political debate or solving a
near-impossible mathematical equation. His Idea of a fun Saturday night was to lie in bed reading a novel or listening to classical music.
