Okay, I knew one of my colleagues was actually a work freak, but to this point...

He's been working for most of the day yesterday on a school project, and so was I. Satisfied with my progress, I push the code with TODOs on things we had to agree on tomorrow as well as mentioning it in the issue associated with it on Git, with my last commit a bit before 11PM.

I wake up, with a ping on Discord asking me what was that "bug" I just pushed, wondering what editor I use and asking me if I even use the console debugger. Said "bug" was the point of discussion I said we wanted to talk about tomorrow, I replied in the morning. But he decided of the fix on his own and committed it, as well as other things until... 3AM...

Honestly, I don't blame him for choosing at our stead, he's the leader of our branch and the Gitmaster on top of that. I just reproach him to call it a bug, not see the issue, and all that while he could, you know, sleep. And get some rest overall.
This dude has been working himself madly these last weeks, where he did about 80% of what each of the team member was supposed to do in a whole semester (which amounts to 150 hours of work) for this project (we're nine folks on it).
Now I'm pretty sure it's how he works and that he still gets a decent amount of sleep (like I dunno, until 9AM or so), so I don't expect a response beforehand.

And indeed, as he woke up, he replied to me.

At 7:50AM.
