I've seen a few similar questions asked, but they don't seem to address my particular situation:
My boss occasionally calls my personal phone (mobile) after work hours on Fridays, usually between 5:30 and 7:30pm. This means that I'm either driving home or have just gotten home (or elsewhere) and so I nearly always miss it. My boss only seems to call about non-critical and/or non-immediate things (e.g., office furniture will need to be moved in the next month, new computers might be delayed, etc.). I would call him back immediately, but it's sometimes quite late and he has very young kids and I don't want to wake them up and/or disturb his family.
I'm still a junior developer and while I don't have many critical responsibilities, I also don't want to seem inattentive. Is it appropriate to respond to my boss's calls by email (possibly giving a short re-cap of the message he left on my phone)? Or should I call him directly? Or should I just wait until Monday before responding?
Edit: Thanks for all the suggestions, everyone! Since a couple people had thought the topic was a bit odd for a software developer, I just wanted to say that my boss and I have (I think) a pretty good relationship and he just wants to "keep me in the loop". E.g., we had a lot of old office furniture replaced and he wanted to let me know that my set-up was going to be changing. Might seem like overkill to some, but as long as we all get along and get good work done, I'm happy.
