His name was Leo and he would become a good friend of mine during the next two weeks. He had a lovely girlfriend where he stayed during my visit. Basically, I slept in his place when he was away.
I also made a reservation for a daytrip in the nearby mountains. We went in the early morning and met again near the Huanchan road, close to the office. A ten-seater picked us up and we left.
I made plans to visit a surfing contest with a girl that I have met on the first day. We agreed to meet at ten in the morning at her place. I couldn't keep my eyes open and decided to quit.
