Ignoring the part about better than ordinary, I felt that it was the perfect encapsulation for the mood I was in when I was trying to write this one, even though that in itself was not as simple an undertaking as it should have been.  I started back in September during a class I was sitting in but not paying too much attention to, as I find that I am wont to do.  I wrote the first two sentences and was rather pleased with myself about them.  But I didn't have a clear idea of where I wanted to go from there, and so those two sentences lay dormant in an unused section of notebook until December.  December was a strange and not altogether wholly satisfying month, and I was feeling somewhat removed and somehow apart from everything going on in the rest of the world, both on a global scale, but also on a more personal scale.  I returned to the sentences, and the rest began to fall into place almost without hesitation.  It had been a long while since I had actually tried to write something, but I suppose it is entirely possible that I have found a style which suits me, one that is both structured and random, formal and conversational, verbose yet not overly heavy-handed.  I think it's also becoming more evident that the words coming out are more and more a consequence of my particular lot in life, as not only here but in other things I have been attempting to write, I'm noticing a slight slant towards metaphors and language that is completely scientific in nature.  But I think there is poetry in science too, and there are sometimes no other concepts that can convey the message I'm seeking other than those that I find in my everyday experiences.   But at any rate, after a suitably long sabbatical, I think I'm ready to resume writing again, though it may not be as voluminous as before; maybe instead of quantity now I can try for quality.  We'll see.
