I was once in an area of Belfast like that, albeit only briefly (thankfully!). It just confused the hell out of me. Scraggly looking kids walking around the street with empty 500ml coke bottles with liquid mercury at the bottom of them?
Was there to visit a friend of a friend (and smoke a bowl

). Went into his terraced house, which looked like a squat more than anything despite being a family home, and went up to his bedroom which also looked like a squat. Filthy mattresses with no coverings on them and alarmingly, again, raw liquid mercury just rolling around the bed? Pretty unnerving just because of the completely alien circumstances.
