The word "why" has haunted my teachers over the past year, any tmie i start a sentence begginning with "Why" they stop what they're doing because they know they're going to have to explain something. But when does why end? (in my case it normally ends with, "Because it just does") For example. Why is the sky blue? Because atmospheric patricle reflect blue light. Yeah, but why do they do that? Well they absorb all the other colours and thats all thats left. But, Why do they do that? Because they just do! Well I've had many conversations like this, and very rarely do I get a comlpete answer, In my opinion Why is the most important word on earth. Has anyone else had an experience like this?
