I am the man Thailand. I prefer English. I could use a good command of English is not only. Maybe I'll talk to you in error, you may not know, and does not understand, but I'll try to learn in order to communicate with you.
I was in Thailand, I do not feel English. I could use English not much better. I could talk to you some mistake. You may not know about and do not understand. But I will try to learn to communicate with you.
