I got a job during the summer holidays back in high school. As a matter of fact, my godmother offered it to me. I thought what could go wrong, especially when you work for a relative, well, a lot :). It was the dirtiest and most disturbing of all the weekend jobs I ever had. What we did was clean old heating pipes in large facilities. We installed a high-pressure pump and connected it to the system. Everything is old and worn out. We had to deal with many bursting leaks that would explode with hot and rusty water.
