WiffleBall Accident

Right now i think wiffleballs SUCK! Today i was pitching wiffleballs to my brother tyler like any other day. But today i pitched one of the balls to tyler and it shot back at me and hit my leg . IT HURT! After a while i looked at my leg and it was all red. Also since wiffleballs have holes there were hole marks and when u rub over them they go up and down ...... KEEP ME AWAY FROM WIFFLEBALLS!!!!!!
