Lately, for whatever reason, I have been thinking a lot about things I experienced in my childhood. I grew up in Philadelphia and lived in a suburban neighborhood of row homes. My elementary school was within walking distance which was good because there were no school buses. Everyday I walked to school. There were two areas where I needed to cross the street.
One day while waiting to cross I was approached by another couple kids who were selling rabbits feet. As I think back on this I am appalled, but at that time key chains with a rabbits foot were common. I don't think I have seen one in 50 years and I am glad about that, but at the time I didn't make the connection between a living thing and this. Long story short, I never got one. I was teased and put upon for weeks until it finally occurred to me that what I was offered wasn't real or real for me.
In the years since, this sort of thing has happened to me again only twice but I remembered the past and was not hurt badly as I was at probably seven. Once you get it, the chance of being broken again is certainly reduced.
So whenever I run into someone who wants to sell me something I hadn't thought about, I take my time and decide if I want to move forward and how. You can't be hurt, if you don't play.
