Are you suggesting she said (the post does not say “shouted”) shana tova with a smile through a thick window? A timid person who the previous days did not dare talking to them, nor knocking on the door, would now shout through the window at people (men) who are praying?
The story is no less beautiful if some details were embellished or misunderstood (I have not accused Aurora of being false; perhaps those people are conservadox, who have been very nice and kind and who did a big mitzva, and were dressed for yom tov, and Aurora is not expected to be able to discriminate, but readers are). The story is cheapened if we force reader to accept all details even when they don’t add up.
