I am tired and exhausted. My brain is fried and I am having problems keeping my eyelids open. I want to sleep but I can’t, another work day has begun. I have no-one to blame but myself. I should not have stayed up until 2:30am in the morning. A reasonable man who has to work the next morning would not have stayed up that late. A reasonable man would have gone to bed at a sensible hour, like perhaps 9pm. I wish I was a reasonable man. Three hours of sleep is definitely not enough.
Still, a lesser man would not have drug himself to work. A lesser man would have called in sick. A lesser man would have been reasonable.
