One thing I'm curious to know, not to derail the general topic of this thread but I'm finding VN girls language ability to be very frustrating. In person I think maybe I can let it slide because they ooze sex appeal and femininity but I wouldn't know until I was on the ground.

To be honest the only reason I'm even considering VN at all is because I've chatted a girl from the big city for a few years, and I know she'd be a sure thing. For all intents and purposes, whether a Filipina knows the population of her own country or how to find the Spratly Islands on a map is not so much important as whether she knows how to turn on the stove, operate a washing machine and keep a baby alive during its formative years.
