This is a fun app.

One way I deal with people talking on speakerphone, is inviting myself into their conversation and making comments as if I were an active participant. That usually earns me a weird look, and then they go off speaker so I can't hear what's been said. Success.

Similar with folks watching reels on speaker, I fake a laugh or make comments about the content. It's awkward enough that they usually stop because they want a moment alone, not an interactive session with a stranger. Which ironically is the same thing I want too.
