What does this mean? Is there a list of approved conversation allowed on trails? What difference does it make if they are talking to someone virtually or physically present on the trail?
I guess it depends. When you're talking to a person directly, most likely your ears aren't blocked. So you get the feedback of your voice levels, and adjust accordingly. This is really difficult to do when you have earphones in, blocking everything. Usually people with both earphones in tend to raise their voices nearly to a shouting level. I don't know if OP does that or not though.
It's more that their full attention isn't on the meeting at hand - how can it be when they're wandering some nature trail taking it all in? If I spent a week busting my ass to get some feature shipped, and in a sprint re-cap meeting all I see is my boss wandering a forest trail going "Uh-hu, uh-hu, wow there's a red-breasted warbler..." I'd become very upset.
I mean. This is a forrest. I barely run in to anybody. It’s not a park.
I’m on mute most of the time anyway, I speak maybe 1/7 of the time on the calls. If I meet anyone in the forrest, I politely say hello to them, and that’s that.
