Beat my head in with a paper clip

Stumbling home this evening, sort of half-blind with tired, I thought to myself: I need a hot bath. Decision made, I sat down with my laptop to unwind, waiting patiently for my water heater to get to work. I read a couple of emails before I realised that my eyes were canvassing words but not meaning. D, Nyx, Pere - I'll get back to you guys when I'm not pulling acts of genius such as waiting half an hour for a water heater I did not switch on.

Exhaustion, your name is fail.
