10. Could you teach me? (That's why God invented the internet.)
Wrong. I would be happy to teach anyone who ask me. Why are everyone being so cruel? Non-cubists aren't bad or stupid.
I've tried teaching a couple of people once... And none of them retained a single thing I said.
I got my cube for a month or so (pb 51), and I have already (tried to) teach 5 people. 3 didn't really get it, 2 did. So maybe it depends on your students?
