Walking along Norlington Road I catch a snippet of conversation from the two boys walking in front. They're aged about 12-14 years old, and the vibe I get is that one of the boys is new to the area, the other has an authoritative tone like he really knows what he's talking about.
"If you go Hackney don't tell them where you're from. If they ask where you're from say E5 or something."
The one wearing glasses doesn't seem to take this in, so the other one has to spell it out for him.
"If you go Hackney right, and they ask you 'what end you from?', and you say Leyton, they'll stab you."
He delivered this chilling bit of local info as casually as telling him which bus to take to get to Mare Street.
It might be that he was putting the wind up a newly arrived country bumpkin in the way that Aussies used to scare me with tales of Brown snakes in the lavvie when I lived in Sydney. But then one day I did come across a Brown snake outside my front door.
It's difficult to comprehend how merely giving the wrong postcode could get you killed and how it is an accepted part of the world that kids inhabit.
