Idiom of the day :- Play ostrich

Usage, examples and definition of the Idiom :-

It was once thought that when an ostrich was in danger it hid its head in the ground believing that if it couldn’t see anyone, no one could see it. That has led to the idea that if people refuse to face painful facts or unpleasant truths, they play ostrich. ‘Play’ here means ‘to act like.’
