I have been working on my PhD from home for several months now because my mom is sick, which was fine with my supervisor up until a few weeks ago. Before starting to work from home (in a different country than my supervisor is), we agreed that we would communicate every two weeks and that I would send reports about my progress.
As I did so over the last months, I would rarely receive a response from my supervisor, who is a big name in our domain and is very, very busy. After a few unanswered emails, I had the impression that I should just contact him in urgent cases, so I stopped contacting him every two weeks.
Now he is asking me to come back to work at the office because he thinks that I have not been communicating enough in the last weeks.
I am aware that I should not have supposed that he only wanted urgent information and thus I should have continued sending him my weekly reports, but how can I tell him that it is because I never got any answer from his side?
My wish is to find a good equilibrium in our communication style so that I can continue working from home!
