I read this short story in 2006-2010. Would like to find it.
My memory is fuzzy but it was probably in my school library, and may have been a textbook, but not a class assignment for me; so middle-high school level
(what makes this harder is that I was in the USA and India in this time period, so not sure which country's textbook it was, although probably India if it's set in a British boarding school).
Written in English, untranslated (would not make sense otherwise).
Summary: There's this student (let's call him A). A is a foreigner and not too fluent in English. The story takes place at a school (possibly a private school/boarding school in England, but not sure).
He bumps in to kids, or some other stupid altercation; the kids decide to bully A. They demand that A "apologize". Some more kids show up to de-escalate the situation. One of them (call him B), understands that A is being bullied, but figures the easiest way is for A to apologize and quickly resolve the situation. So B says (approximately) "be a good sport and apologize". Finally, A is overwhelmed and runs off crying (approximately) "I'm sorry, I no know apologize".
