Hi, sorry if this question is out of place. I got banned from r/Thailand 3 years ago for making fun of a video of Chinese tourists literally pissing on the BTS skytrain.
My gf is from Ubon, and when she speaks Isan I only understand around 10-20% of what she says. Any educational books that I can buy in Asia Book / Kinokuniya or other bookstores? Thai or English book is fine, but English would be preferred
