It was all a bit of a joke to Jeremy,which is why such a nonentity had the temerity to carry it out in the first place. He was a relentless tease at Gresham's,he rode a bicycle round in circles at Ann Eaton,he played practical jokes on friends for a giggle,anything to relieve the monotony of working life on the Farm. Nobody read the signals,the parents did care but they didn't act as if they did care,they were not tactile and as Jeremy moved from one closed institution to another and witnessed the failing health of those around him he must have sought a way out of it,though even he himself baulked at the ultimate solution,one of actively killing them all by gunfire and not passively standing by as the Farm burned down with his parents inside.
