Michel had indeed not left his apartment. In fact, he hadn't slept at all that night. With a splitting headache formed from a combination of factors, he just couldn't do it. He did try though. Sort of. He tried propping himself up in his bed so as not to roll over and bleed all over his sheets. Unfortunately, the discomfort was already too much for the bed to make much of a difference. So, instead of sleeping, Michel decided to stay up, idly wandering around his apartment to try and cope with the pain. He did anything that didn't require thinking about what had happened that night. However, he bumped his head into the unforgiving beams of his ceiling far more than once. He had a small cut on his forehead from that as well. The injured parts of his head were covered with the handkerchiefs he had finally found, though it was messily done and it didn't necessarily help with the bleeding as much as he had hoped. After awhile he assumed it had stopped, but he wasn't going to untie anything and accidently cause it to start again.
It wasn't until much later into the new day that he finally managed to fall asleep in the chair he had closest to the fireplace. And even then it was only accidental. He had sat down for a moment to get warm only to find himself dozing off out of sheer exhaustion. It really wasn't that bad, as he didn't imagine he could've gotten to sleep otherwise. It had only been a few hours like that before he was awoken by a knock on his door.
He stirred in his seat, groggily opening his eye and wondering when it was he had fallen asleep. And then who in the world could've been knocking on his door at whatever time of day it was. "No one's home!" Michel called. It was a very obvious lie, but that was usually enough to drop the hint that he didn't want company. They would likely go away unless it was really that important, but he was not getting up to answer the door for them. It was warm by the fire and he was much too tired.
