I remember reading a story that a Japanese middle school equivalent class got to raise two pigs to adulthood.
Feeding, cleaning, exercise duties was assigned to the children.
Then one day, the pigs disappeared, and the children were treated to pork products...
The teachers explained that that was the way of livestock, and the kids should treasure food from a living being...or some shit like that.
Kids got to take home lots of bacon and pork cuts...I wonder if the author read that story or WAS A PART OF THAT CLASS.
