Reminds me of how torturers in the 'dirty wars' in Latin America were seen by the victims to leave when their shift finished and another one came on duty to continue the torture. But often they'd come back, having evidently gone home, had a meal with wife and children, but then couldn't resist coming back to 'enjoy' more - so they no doubt made some excuse to their wives about being very busy at the barracks, and rejoined the torture squad!
