No he doesn’t respond (or check?) outside of normal office hours. I’ve already sent a cancellation email about an hour before the end of his work day, and my appointment is the first one in the morning. I have to assume he took me at my word that I’m not coming at 7:00 tomorrow morning. Honestly, if I showed up after the cancellation email it would just be awkward. I told him I was aware that I was acting like a complete weirdo and that I’d be back to normal by next week.
