This whole exercise is about the learning experience and it's all been pre-arranged by my brother. My nephew would never be allowed to knock on random doors and wander about without supervision, it's far too dangerous, probably for different reasons than in Pakistan, but dangerous all the same.
I'll probably do a post on his progress eventually and maybe also for when he buys his first Lego with money he earned himself.
He's really a good kid and is learning some great lessons, developing his personality, and gaining valuable skills that, once part of his nature, will help him navigate what's going to be a very complicated world when he's older.
