Thank you for writing, nice to see your message.
You write English pretty well. Maybe you can speak English better than you think. But I'm happy to help you, but I'm not sure I would be a very good teacher.
Facebook - no,not really. I don't like it. I have an account that I check about once a month, but that is all. What about Line or Whatsapp?
Do you ever go to Rayong? I've been once, for about one hour - that's it. I should travel in Thailand much more.
