When it comes to functioning on very little sleep, I am a lot like those wind up toy thingies one use to be able to get from say, a McDonald's happy meal. Although I think that now, one would only get some choke-stabbing-std-devil juice-proof-led paint-free plastic figurine that does nothing cool, not even glow in the dark.
But as I was saying, whilst awake on very little sleep (like today, where I showed up to work at 6:50am), I am like a wind-up toy that you have to push a few times to rev it up then let it go and it rides around all by itself for like, three feet. I only have about one day of staying up late/getting up early energy in me, then I wind down completely and things get really weird.
That is all.
