You are a fox. Up until recently, you lived in a city with lots of loud noises and loud humans. You stayed hidden most of the time. Recently, the ground shook and you hid underneath a large structure until it ended. When you went outside, it was silent.
There were no humans around, not that you could see, so you decided to go try to find some scraps to eat. Overturned bins supply you with a large amount of food every week, enough that you can live off a meager diet of rats and mice, when there is nothing else.
The silence is eerie to you, it unsettles you. You eat quickly and leave the area, hoping to find any noise.
