hop

My current background music is a constant chirp from a cluster of birds, and this is a novelty in a city or a country where birds were killed by the millions.

A non-stop avian conversation is reassuringly more calming than any man made noises; perhaps a consolation that all is right with the world..  no signs of radiation.
  Just a comfort to know that there are other forms of life, living, breathing, existing along with you.. that you're not alone.

It's difficult to not feel lonely especially when you want to be alone. When you're not seeking desolation, but only hoping for a bit of comfortable isolation. When you want to be conveniently withdrawn, but fear being forgotten.
It's fun being a recluse until people stop caring.

There's soft trill and loud warble to remind you of the world outside, that you can be a part of the microcosm anytime you want.

On the other hand however, who wants to be a part of that terrene when your entire megacosm is shrunk to backlit gadgets?
  I know someone out there might suggest an app that imitates real chirruping of birds, and an update might even add roosting songs to it.
You've got the whole world in your hand, for reals.
