Hello, my name is Lisa. I come from Tegal. I am so grateful to be here.

I have an interesting hobby that I want to share to you. I really love swimming. I used to swim twice a week when I was in Tegal. I really love it because it makes me healthy and fresh all the time. I happen to like swimming when my father took me to a swimming pool when I was a kid. He taught me to swim because I used to complain about why my father has a very tall body. He said to me that swimming will gain my height. Therefore, here I am. I sometimes think that I want to be an athlete or a diver. That is all I can share with you, guys. If you have some questions, just ask me. Thanks for your time.
