Why would you treat working from home any differently than working from the office? I wouldn't work until 8pm in the office, so why would I do it at home?
The special scheduling of personal appointments doesn't make sense to me. If you were in the office, you'd tell people "I'll be away from 1-2 today" and that's it. I do the same thing when I'm working from home.
Maybe I'm weird because I'm not big on socially hanging with my coworkers, but the face time doesn't bother me at all. We do a lot of video calls, I see them plenty.
My work is not my life. I've never had trouble separating work and home life. Working from a room in my house has never changed that. Now if you'll excuse me, I have some yard work to do on my lunch break.
