thank you., for the concern., when I was young, my parents took me to visit my relatives in the provinces., I got into the water to get to the opposite side. relative of mine was saying it. There are leeches in the water, I was so scared that I cried. was the first time I knew about leeches., when I graduated from high school I had a friend that left seven people, we tend to do funny things when I think of a story. It makes me smile
