It wasn't that dangerous but it's etched in my memory. I went to a boarding middle school. The school was outside the city and in the middle of some farms. There were shepherds there that used to graze their sheep. Anyway one afternoon we were playing soccer. The ball landed on the other side of the school wall. I jumped to the other side to bring the ball back. One of the shepherds saw me and sent his dogs after me [probably for fun]. At the time I was terrified of dogs. I was so afraid that I immediately climbed the three-meter wall injuring my hands.
