I remembered an episode from religion class in the mid-1960s. I must have been in the fourth or fifth grade. We were told that on the Day of Judgment, everyone on Earth would see themselves exposed for all their human failings, and would be horrified to discover the extent to which each of them were unworthy of Heaven. Such would be that horror, that we would fail to notice anyone else's nakedness but our own.
I don't know what made me think of it today. It is a more believable scenario than the one depicted here, but the ending is about the same.
