I work in a small startup in the EU, and was teleconferencing with my line manager. I was on the train so connection was not so great and I was off video.
However, as I had just learned about a family member's illness, even though I was not emotional about what my line manager and I were discussing, I could not stop thinking about my family member, and my voice broke more than once. I think he might have either thought that I was crying or that I was emotional about what we were discussing.
We were speaking about my role in his team (we are a three person team), so it can be construed as though I was emotional about that, which I was not.
I do not want him to think that I am an overly-emotional person, or that I get emotional about my work (it's just a job). How do I mend any false impressions of myself?
