I can kinda get behind this. I mean i already have lots of practice avoiding people, and I live in a midsize city. I don't see anyone without an appointment, and I imagine those will be quite few during the apocalypse. (To give some idea of how introverted I am, my life was not at all upheaved by the lockdowns.)

The only drawback i see is that I do not like "nature" but if civilization collapses I'm really not going to have much choice about being in it.
