I remember when I was a child, my family lived in the mountains, when everyone went to the public toilet, there is a toilet near my home is very small men and women only one location, in a small hill below. One day I played alone in the mountains just climbing up the hill to see a woman dry well to stand up in the toilet, is lifting the pants, only to see two white thighs, when the heart beat wildly for a long time. Now think about it is still very interesting.
