The lamp wouldn't turn on. He struggled with it for what seemed like half an hour, swearing under his breath, and then swearing out loud, loudly out loud, freaking out both of the cats in the apartment. He would apologize to them later. Anyway, they should be used to it by now.
And then once he got the damned thing on he couldn't turn it off.
He wasn't going to waste half an hour on this useless project, too. He wanted to go to bed. He simply unplugged the lamp. That turned it off. That worked. Now the apartment was dark. He felt his way to his bed. He was asleep in minutes.
He awoke sometime later. He wasn't sure how much later. And he wasn't sure what was wrong. It took a few seconds too many to figure it out.
The lamp was turned back on.
