Dangerous childhood?

When you grow up your parents of course want you to be safe and have good friends. My mother decided to help a neighbour with her son during day-time when this neighbour worked. So this young boy was playing with us all day long for some time. Later on in life we realised that the child we had at home became a notorious criminal/bank robber who served 12 years in jail.  A member of militärligan.The creme de la creme of the police had to hunt him down. So I can say that I hanged out with a dangerous criminal in my young years.
