My boy has loved Star Wars for a few years. He’s watched all of the Clone Wars cartoons, and all the movies except #3 – he’s only six, I don’t let him watch a hero of his become evil, kill children jedis, attack his wife and have his legs chopped off. Now he’s particularly keen on SWTOR. 
Instead of keeping it a private hobby, I talk to him about it, and try to use it for education purposes wherever possible. Today we used Lego so I could show him a triad, which we’ve talked about before as he knows I’m a healer, and he wanted to put it on his website. I wanted him to learn about diagrams and using models to show an idea.
Check it out. He’d be delighted to read a comment or two.
