Think of all the roads, think of all their crossings. Taking steps is easy, Standing still is hard. Remember all their faces. Remember all their voices. Everything is different, the second time around.
THIS IS EXACTLY WHAT YOU WOULD HEAR IN CASE OF A NUCLEAR ATTACK
Many countries have systems that allow them to speak to as many people as possible in case of something catastrophic.
The United States has the Emergency Alert System. When triggered, the system interrupts all T.V and radio systems to speak.
This is what it sounds like.
The most creepiest and terrifying noise and voices ever.
