isn't the sky blue today?

This reminded me of a conversation I once had with a certain brother of my dear friend Mr. SK. It all started when he was gibbering some philosophical jargon and much to those listening's dismay couldn't seem to keep an 'ordinary' conversation, so in hopes of possibly upping the participation of all those in the room, I asked him if he be as simple as to you know, talk about the weather... I started with, "Isn't it a nice day today?' ... "What a beautiful blue sky." To which he philosophically ask me, "Is it really blue?!" "How do you know it isn't red?" Then he proceeded to tell me about why people see 'blue' as the color of the sky... I-yah! Of course, it was completely informative, but an utterly hopeless attempt at a non-involved light conversation. After all, last time I had checked I wasn't sitting in a classroom or in front of a '3-2-1 Contact' program.
