it is unfortunately not at all similar. I am not going to dedicate the time and energy necessary to learn "another impossible Asian language" and this is why I am intentionally moving to an expat area where the local language will not be necessary. Perhaps this is a bit lazy but not only do Vietnamese and Thai not have anything in common with eachother, they have nothing in common with any other language either.

I will likely just learn polite phrases like hello, goodbye, thank you.... etc.
