No circuit assembly, convention, how we can't fellowship at the k.h. disappointed we might have had a love one die, etc etc. He then goes on to write about how disappointed Jehovah must have felt when his first human creation rebelled. Yep it always goes back to Jehovah! Nevermind you worthless maggots! What about poor old Jehovah?! You should feel bad for Jehovah! Facepalm
