Hello Won.
Thank you for your reply.
I got it. You had to worked a lot.
Take a rest much and do the things you love when you free time.
Actually Thai people interest in English language but we doesn't use English common. So sometimes it's hard to communicate with foreigner, but I guess it's Okey about young or new generation are smart more than me a lot. There are a lot of foreigner come to travel in Thailand. So Thai people are so familiar with foreigners. Also we're usually so kind with foreigner. Yon can have fun when you travel in Thailand.
