would love to hear more - what kind of work, what is home base like, how does the kid socialize, what age did you consider, how do friends come and go... I'm thinking hard about this.
Socialization of kids is a uniquely Western obsession, I think— not an issue here because it's a child-friendly culture with lots of social interaction. The average age in the Philippines is 22, much lower than in the US, UK, or Canada. That means there are children everywhere here my son makes friends easily.
As far as our friends go, we meet up with people wherever we happen to be. Sometimes we're in a place where we don't know anybody, but then we just beach bum around when not working.
