You're mid-sentence about something that genuinely matters when you notice their eyes have that glassy, downward tilt—the universal sign they're reading a recipe they'll never make. You pause. They don't notice. You wait longer. Nothing. Finally you say, "So anyway, I'm moving to Portugal," and they go "Mm-hmm, sounds good," still scrolling. You're now contractually obligated to actually move to Portugal because a witness has been established, even if that witness was really just a pair of eyeballs and a notification badge.
