At age 13, I was violently mugged at a busy train station. There were dozens of onlookers, but none of them lent a hand ... That was a defining point in that stage of my life. After that, I could never tell myself that it was someone else's problem, or let a situation pass me by if I felt something had to be done. I knew from experience that all too often, no one else would act.
