(I tried to avoid doing cross-post, but I think this is too cute to not share and it gives me an excuse to put Ninja legitimately in a post title!)
My seven year old daughter Alice announced she wants to be a ninja when she grows up. She’s already formed a secret ninja club (girls only) in her class. And after homework I was press ganged into making ninja stars from tin-foil and cardboard and my wife made braces from black velvet so she could start her ninja training. She plans to train every day.
Of course she is young, she has much to learn and she had many questions, like, how do ninjas train? What do they actually do? What weapons do ninjas use besides ninja stars (toilet roll nun-chucks are planned)? Hmm she is wise. 
(Someone has already kindly pointed to the Ninja-shirt-technique. This will be tomorrow’s Ninja training!)
She is a very cute ninja.
