A childhood belief about periods

I did not know much about periods, My mom tried explaining me about the blood stains. " I just laughed and I told her I am feeling well. Why on hell will I be bleeding? And arrogently told her that U think too much about all dangers and diseases". She never again tried explaining . And finally when I got my period I was scared that I had CANCER and decided So only mom was telling me all that stuff that day. I went and told my mom about that when she explained That I was not having CANCER. It was really hard to belive that day. Hahahaaaaaaaaa......
