I met people who were like this. I meet a guy who retired to Bangkok. He would complain about the free loaders in the US and how they didn't try to fit in. You guessed it. Doesn't want to learn Thai because has has his girlfriend to translate everything.
I went out with a friend I met who has been living here for 3 years. It was him and his girlfriend plus her friends. They were talking shit about him in Thai and when I spoke in Thai they immediately shut up. Wouldn't you want to hear what people say about you? You know it happens here a lot. I have heard people talk about me on the BTS and I let them know I can understand them.
