Procrastinating Sleep

Why do I do this? I'm tired and I should be sleeping. Yet I find myself fighting sleep by surfing the web. Maybe I have a lot on my mind and I'm trying to avoid the quiet time before slumber that allows thoughts to become unavoidable. Maybe I'm just being a kid and fighting sleep simply because I can. Maybe that lovely Sunday afternoon nap threw me off schedule. Well, whatever has caused it I sure am procrastinating going to sleep.
