The Huachiman

The "Huachiman"... how many times have I heard this expression now? No idea, but it still makes me smile every time. First, I thought it was some kind of savvy old man, but in fact it's only a localisation of the term "watch man". There are plenty of these guys in Miraflores, so you might hear the term frequently, yet you never quite catch why they don't simply call them "guardia" or something...
