How did Chandra's classmates treat him?

From the text:

Coaxed by his father to excel at studies, he was perplexed for the lack of aptitude. What's worse, the antics of his classmates made him hapless -- they marginalized him at playtime, for his lack of reflexes, and, for want of grace, targeted him at fun-time. Well, to cap it all, the snide remarks of the have-nots, that he chose his father well, induced in him a vague sense of inadequacy.
