Something I saw a while ago, back when my personal "posting around the clock" rule couldn't be in effect. A blind couple, with canes and sunglasses, guiding each other around. How does that even work? It sounds like something out of the Bible. I'd guess that the man had more vision than the woman, but they were both wearing sunglasses. The guy was way more assertive with his cane, waving the tip around like an earthquake detector, while the woman just waved hers around gently to check for anything the dude might have missed.
