Yeah my niece told me she was taking ninja classes, I was like yes! Then found out it was that silly obstacle course thing, lol. She is a beast and needs to be learning to harness it with some true martial arts, but my sister and her California bred husband are all anti violence, lol. So that is what uncles are for, lol. Worked for my daughter, she can kick some ass and walks around with 2 blades on the ready, lol. Raised right, lol.
