OMG! I cant believe I saw this post. I never post but I was actually there and saw the whole shebang! She wasn’t tzenua and all the guys were averting looking at her! They were turning away their eyes and heads from her even before she tumbled over… So most of the guys may have not even noticed. And if some did hear the fall they didn’t want to look at a non-tznius girl! And they are right!!
Plus there were ladies there who were able to help the girl without needing the “guys” to get involved.
