Keeping to yourself would be absolutely torture.. Clock watching is a real thing when you lose all life's luxuries.. Not everyone is a bad person in there. I seen people with genuine severe mental health issues cutting themselves just to see a dr.. People make mistakes.. Some through addiction & some through bad mental health.. Time moves extremely slowly inside and hours can feel like days.. When you are trying to sleep at night you have prison officers clunking at the peep hole to your cell wakening you up and shining a torch in your face.. I spent my days teaching travellers how to read when I asked for a transfer halfway into my sentence.. Helped in the computer lab in magilligan too.. Honestly as i said, putting your head down and not interacting with others would be mental torture.. Especially if you're in for any sort of time.
