Sometimes it will be 4:09am and I'll think: why is it that I'm still awake? I've given it some thought now, and I am starting to conclude that going to bed is actually a skill - a talent in which most people demonstrate an innate ability, but at which I am personally quite useless. I mean, it's 4:12am now, and I should have gone to bed many hours ago. But at the point at which even the bed-postponing activity of "messing desultorily about on the Internet" has tapered naturally to a halt, and lost its tenuous grip on whatever highly-questionable claim it may have had to justifying my sustained consciousness - even then - rather than go to bed, I have come here to write this.
That is how useless I am at going to bed.
