On the door, there is a sign. "Do not disturb," it says. The sign is completely unnecessary because nobody hears you here from the outside. The windows are closed. You have no choice but to sit down and wait on a very uncomfortable chair.

Normally you fall asleep after a while, but not tonight. Tonight you came prepared with a gas stove. There is a water dispenser down the corridor supplying you with water for instant coffee.

It is worth the wait. After a while you hear it: the scientists are imitating the recordings. It starts with the easier species such as goats and cows. One scientist with a particularly deep voice imitates a sea elephant. It is beautiful.
