“We're all here to take care of ourselves, and ourselves only. This is how I look at it: if a gunman rampaged through the flats, I'd barricade Mum and me in our place and forget about anyone else on our floor. If the gunman broke into our flat then I'm not entirely sure I'd take a bullet for Mum, or vice versa. When it comes down to it, we're all on our own. Once you realise that, life becomes simpler.”
