I find myself uncomfortable with the title of this question, but don't want to get into an edit war, and the question is at the moment both protected and close to closure: Is it bizarre that a professor asks every student for a 3 inch by 5 inch photograph?
Calling any action by a staff member bizarre just precludes a sensible dialogue or response in my view. Perhaps the question wanted to find out how unusual is the request or how widespread this type of thing occurs.
Should I have just toned it down by an edit?
The Cambridge English dictionary gives these synonyms:
Whereas the Oxford gives these:
strange, peculiar, odd, funny, curious, offbeat, outlandish, eccentric, unconventional, unorthodox, queer, unexpected, unfamiliar, abnormal, atypical, unusual, out of the ordinary, out of the way, extraordinary
fantastic, remarkable, puzzling, mystifying, mysterious, perplexing, baffling, unaccountable, inexplicable, incongruous, irregular, singular, ludicrous, comical, ridiculous, droll, deviant, aberrant, grotesque, freak, freakish, surreal
So even the dictionaries have different views of the power of the word!
