My left knuckles are kinda sore, which is a new one to me

Okay, self, repeat after me:

We should not stay up and ink a few more drawings for our commission. We can do that tomorrow afternoon. Or some other time of day after we wake up! We finished the majority of the drawings for the commission, and we have plenty of time to finish the last two. Even if we didn't, our friend will understand. Worst case scenario, we can probably dig up some old art and use that. Right now, you need to sleep, and/or do things that don't make your hands hurt.

Got it?

Okay.

You can do this.
