I don't think she heard anything. I actually didn't notice her at first—I was facing sideways and minding my own business, and it's not like she had two heads or was walking a capybara down Bloor St., or anything else that would have differentiated her from any other passerby. People wearing niqabs aren't uncommon either where I live or where I work. So by the time I realized that the drunk was shouting at a particular person, she had almost passed by, plus there was the noise of the construction.
