There’s nothing “just” about “just hopping on a call.” Let's say your colleague asks you a reasonable question. You could take 5 minutes to write a cogent reply. But instead, you say, “Let’s hop on a call.” When you say this, sometimes what you really mean is: “I don’t want to do the work of clarifying my own thinking. And I believe it’ll be easier to think out loud and answer in a live conversation.” My response to you is: I do not want to hop on a call because you are too lazy to write a cogent message. If you don’t want to invest a few minutes to write a reply to a reasonable question, why should I listen (with no 1.5x button) as you meander in real time? GTFO. To be clear, I am not blindly against live meetings, nor am I blindly in favor of async communication. There are plenty of reasons to hop on a call, and I hop on calls all the time. But let's be intellectually honest about whether we could share a perfectly good response in writing, if we took an extra beat.
