Can you imagine clapping… and getting clapped back half a minute later?

In some truly huge places, sound can bounce around so much that the echo takes ages to return. A famous example is in very long underground galleries: echoes lasting dozens of seconds have been recorded, as if the air needed a moment to think up its reply.

The funny part is that when an echo arrives late, your brain reads it almost like it’s “something else” rather than your own sound. That’s why in caves or tunnels people end up speaking softly… not out of respect, but to avoid summoning a “second me” on a delay.

Magikito conclusion: if your words come back late, it wasn’t indifference… it was sleepy acoustics.
