I’m tired. 

I haven’t even done anything today. It’s always the days when I do nothing that I feel the most tired by the end of it. 

Even days when I wake up at 7am, I’m out all day, socialising and interacting with people, talking for hours and hours and hours, I don’t feel this tired. 

I’ve got some theories. 

The one I like most is a theory I only recently came up with. 

I think that humans all have an interconnected energy source. Every human is plugged, wirelessly, into a font of finite energy, and every day, we draw from it to do the things we do, even if that’s just sitting at home, doing nothing but watching television. The more we do, the more energy we take from it. 

Introverts are the “standard” energy sink. They take only as much as they need for the day, and allow it to be spent over time, exhausting to zero at the end. 

Extroverts are irregular. They take what they need for the day, but instead of expending it, they take more and more as the day goes on, ending the day with a massive surplus of it. 

Because of them, there isn’t enough energy for everybody. 

So how does the system compensate for this? 

I bet you’ve already come to the conclusion yourself. 

It’s all because of those damn extroverts that I don’t have energy today. 

I’m sure there’s other, more important implications of this theory of mine to ponder, like the fact that if it were true, we’re probably running on a sixty-four-bit equivalent of some alien’s computer who’s playing Alien Sims 4. 

But I don’t have the energy to ponder them. 

Damn you, extroverts.
