Yes, that is the question. We have a private room in our home situation. We were lax about greeting guests. If we were here, great. If not, we let them check themselves in and gave some directions, and maybe would bump into them during their stay.
Then, we stayed in a private room in a house when traveling where the host(s) did not greet us and seemed to be hiding the whole time. We thought that was super weird, so then we decided to try to at least greet our guests upon arrival, and went out of our way to make sure one of us was home. We then found that some folks seemed put off by it. Those folks were always the ones we had issues with, too, like ignorning house rules or being a third party booking (always parents of an AirBnBer), so we knew we had to greet everyone now, right?
Then, we had friends tell us they never get greeted, even at home shares, and sometimes never see/meet the host, and were totally okay with it - preferred it - especially since they didn't have to be there at a specific time to check in.
So, home-share folks, do you greet your guests? Whether you do or don't, how is that going for you?
