What's that Again?

It is startling to find out that one no longer understands what he used to get almost instantly. It's like unlearning something that had once been a central part of you. I thought things as important as that could not be unlearned...kinda like riding a bicycle (though I wouldn't know firsthand because I don't know how to ride one). I guess I was wrong.

And why the heck am I feeling sad about this? It was almost a conscious decision.

Oh...that's why.
