I keep coming to Vientiane for relatively short periods (around 2-3 weeks at a time) dealing with an ongoing project. I've been here at least 7 times in the past 3 years I was thinking I could do a few hours a week learning something useful.
I've heard Lao and Thai are mutually intelligible so I thought maybe learn some spoken Thai to have a wider use than just Lao. I am not so concerned about written forms, just day to day chit chat.
From what I've seen, French will not be of much use day to day but could be of use elsewhere (I already have basic French to school level).
So, what should I learn, Lao or Thai or not bother with those and do some French conversation?
