What?

 What is a "teardrop on the cheek of time?" I heard this phrase used in the context of a world heritage site, but the beauty and appropriateness of it struck me immediately. What is your answer to the proposition that a natural or supernatural entity could evoke a feeling of sadness transcending the short term? For one thing, I say the death of a good person, gone unnoticed but to God. Comings and goings of angels and visitations from God often go unnoticed. Questionings? Yes. Acceptance not so much.
