What would yield the greater benefit to mankind: if I spent the afternoon taking stock in my dispensary, or if I went to the beach and took off my clothes and lay in my underpants absorbing the benign spring sun, watching the children frolic in the water, later buying an ice-cream from the kiosk on the parking lot, if the kiosk is still there? What did Noël ultimately achieve labouring at his desk to balance the bodies out against the bodies in? Would he not be better off taking a nap? Maybe the universal sum of happiness would be increased if we declared this afternoon a holiday and went down to the beach, commandant, doctor, chaplain, PT instructors, guards, dog-handlers all together with the six hard cases from the detention block, leaving behind the concussion case to look after things. Perhaps we might meet some girls. For what reason were we waging the war, after all, but to augment the sum of happiness in the universe? Or was I misremembering, was that another war I was thinking of?
