About three months after starting secondary school, my Daughter proudly came home with a letter from her maths teacher inviting her to take a test for junior mensa. Of course her mother and I were proud to read such a missive and told her that it was her choice she could decide to take the test or not. She told us she would think about it.
A few days later I asked her if she had decided to take the test.
Her reply proved to me that she didn't need to take any test to prove her intelligence, it was something like this:-
"Well dad, I've decided that I won't take the test, after all, they charge a fee, I think it would be a bit stupid to spend good money just to get a Certificate proving what people putting me forward for the test already think I am".
