You ask your coworker if he wants coffee. He stares at his monitor. You ask again—louder. Still nothing. So you stand there for thirty seconds, then just get him a coffee anyway, and watch him drink it without once acknowledging that you exist. Two weeks later he complains to someone else that nobody ever offers him coffee.

I ask my coworker if she wants coffee. She stares at her screen. I ask again—nothing. So I pour her a cup anyway, set it next to her keyboard, and leave. Twenty minutes later she emails me: "Why is there a cup here?" Apparently I'd been talking to her the entire time while she was on mute during a Zoom call with her camera off, which means she was actually just napping.
