AE - a question if I might.
If a person builds and sells a house and that house should collapse that night and kill the new owners, who is at fault?
The neighbor? If he coveted the house and hated whoever owned the house, not likely.
The owner? If they didn't maintain it properly, maybe but not overnight.
The builder? If he didn't build it properly, definitely.
Does it make any sense to blame the neighbor just because they are a lying, envious, self centered, reprehensible tool?
