Danged lumberjacks.
They leave the forest, go to town, get all ‘liquored-up’ and wanting to chop down people because they are vaguely tree shaped.
It’s even worse with the hunters. After a few days In the woods with their eeevil guns, they become crazed, go into the nearest small towns, rape all the women, kidnap the kids, murder the men, and leave the towns bullet pocked wastelands. But be of good cheer; it’s not their fault, it’s the guns.
