When I was ten, I read fairy tales in secret and would have been ashamed if I had been found doing so. Now that I am fifty, I read them openly. When I became a man I put away childish things, including the fear of childishness and the desire to be very grown up. – CS Lewis
I know this quote very well, but I just saw it in the blog article KJ Charles wrote, so to give extra credit - I copied it from there.
