The End of the World

I've finally made it back to the guides neighborhood. It took a lot longer for that office building to empty out than I expected. I had little trouble finding my way back, but I did more slow.

From where I sit I can see several zombies moving behind curtains and through lit rooms, in what appears to be a happy and comfortable life.

How to communicate with them safely? It is a question that will keep me up most of the night.
