Peace, my friend at work I use my bathroom sandals, and after about an hour of time I put on my sandals and I stabbed me with a pin at the base of my leg. The pin was stuck to the sole from the bottom and it only appears when I stepped my foot into the sandal. I am afraid if he has pricked my friend and some blood was stuck in the socket between the head of the pin and the surface of the sole (it might be like the socket of a needle). Pricked.
Note that my friend is sexually active
