There are certain types of puzzles, like Su Duko, which are fairly easy for me. Other puzzles, like the infamous Rubik's Cube, I grade out at an F-. Anyway, I'm a fan of puzzles and games, but unfortunately don't do nearly enough.
I taught a stripper friend how to solve the Su Duko Puzzles and she did very well*. I assumed that I'd just imposed my values onto her and that she'd move on to her interests. It felt good to see that she'd purchased a book for herself and was working at solving them. And, she had taught her sister and was trying to teach some of her fellow strippers (it can get boring and slow in a club).
Upon seeing the book and talking with her, I was also very surprised to learn that her Su Duko skills were going downhill?! She showed me the book with the half finished puzzles and sure enough her ability had dropped dramatically. She says was doing very well and even improving and then it just became more and more difficult for her to solve even easy ones. I was thinking perhaps that is why she had so much difficulty in school---she learns and improves and then poof! :(
On the more upbeat side she did get involved in online puzzles and learned that she does have an aptitude for some of them. And, she was very happy to learn that there were certain puzzles that left me floundering. :)
