Critics who treat adult as a term of approval instead of as a merely descriptive term, cannon be adult themselves.
To be concerned about being grown up, to admire the grown up because it is grown up, to blush at the suspicion of being childish: these things are the marks of a childhood and adolescence.
When I became a man I put away childish things, including the fear of childishness and the desire to be very grown up
~ C.S Lewis
