Anthony's discomfort did not die, so he simply had to try and get used to it. That did not happen, no matter how long he waited and tried. He felt kind of hopeless, really — for a brief moment, he thought that maybe it would be best to just give up on being angry, and let whatever happens, happen. He eventually compromised with himself, and permitted himself to let go of that anger until tomorrow comes. Then he can be bitter again. Eventually, after what felt like hours (but was in reality probably only minutes), he managed to fall asleep yet again. It wasn't that he was comfortable enough or relaxed enough to do that — it was just that the tiredness was overshadowing everything else.
