Thai Crash Course In Bangkok?

Hello everyone,

I am from Hong Kong and I have just started my trip in Chiang Mai and going over to Bangkok later. Being mistakenly recognized as Thai all the time when I am here made me think that it would be fun to actually do an intensive crash course when I am in Bangkok so then I can interact with people. This is already my 4th or 5th time in Thailand and I enjoy everytime SO much the food, the culture, the shopping and the Thai massage.

I am wondering, have any of you come across good one on one classes that you can recommend? I want to focus on survival skills...so probably would be very much focused on conversation and recognizing basic signs.

A little bit about my language background, I am very interested in learning languages and Thai will be my 6th language that I attempt. I speak Cantonese (native), English and Mandarin (very well), German (also pretty well) and French (need probably to refresh that... ). I would love to learn Thai as much as possible so then I can put it in practice on the street!
