Ha, ha, sounds like you're making yourself useful, which must be good! My wife's family is based in KL but despite annual visits since 1997, I still don't know the city, apart from a few places. KL is forever changing and expanding.

My introduction to Bahasa started at the airport, the first time I set foot on Malaysian soil, when I heard "penumpang-penumpang" being repeated on the tannoy.
