I don't know my neighbours names. I do have the excuse of only being in my current house for just on a month.
I find it incredible that you could live next to someone (in a block of flats) and not know that they had been dead for a year.
Do you just lie in bed at night and think gee I haven't heard Bob go to the toilet this month, I hope he is OK.
These are stories you hear in large metropolitan areas like London or New York, not Wellington.
