my great experience
It's been a long time since I didn't opened my italki account and I really miss it.
So, in this moment I want to tell you about my experience. Last month, I went to Japan as a participant on the Jenesys Program. It was really fantastic there and I got so many first experinces, such as first time go abroad, my first winter, my first snow, first time going to an onsen, first time staying in a ryoukan, etc. I feel so lucky that I went can go there and I wish I can could get one more chance go back there again.
