If you can get Skype to work, we can try using that for video conference. It is very different than writing a letter or talking on phone. Maybe a little scary because you really see what other person looks like and acts like.
You write ".I have a friend to marry with Denmark man. Now she moved there is a little boy." but I don't know what you mean. Man have little boy? Man act like little boy? Your friend have little boy with man from Denmark? Sorry, sometimes when writing English it can be mis-understood.
I first went to Thailand in 1988, I was working on an electronic product and a factory in Thailand had experts to help with the production of product. So I ended up going to Thailand many times, up to about 1994. I even learned to speak a little Thai, but now I forgot most of it and would have to learn again many words, and to understand the alphabet, it is difficult when you are not so young anymore, to learn new language new alphabet. But Thai is beautiful language. I met many Thai people and got good feeling especially the Buddhist culture and how it affects people's manners and relationships.
