Note that Perry doesn’t have this problem when she leaves a venue and must run a gauntlet of fans expecting an autograph or a few words. Perry does what she can, moves on, and the lost opportunities dissipate. The body is its own flow control. We can’t be in more than one place at one time. At a crowded party we inevitably participate in less than 5% of the conversation, and cannot read up or catch up on the remainder. Photons that miss the retina aren’t queued for later viewing. In real life, packet loss is almost total.
