get the kids school books for reading...start at Bor 1....as almost all Thais learn this way finding a teacher is easy. You can learn with kids and adults. You can learn to write as well.
at first you will sound like a kid and Thais will declare nah ruk jung poot muen dek leuw.....totally loveable you speak like a kid
I learned to read, write and speak functional Thai in about 6 weeks. I finished Bor 6 in after 2 months.
I met many girls while studying on buses, trains and beaches. They helped keep my enthusiasm level high. After Bor 6 I studied less as I spent too much time looking up words in the dict or dictionary.
