A young teen of my acquaintance (going on 14) doesn't like the sound of a nearby train. It sounds to her as if the universe was rushing at us to consume us (or something of that sort -- I forget the exact phrasing). I tell her that to me, a train is the sound of heading off to adventure. She exclaims most earnestly: "I don't want any adventures! I just want to sit in my room and draw!"
This young woman is a highly talented cartoonist, and does indeed like to sit and draw (and instant-message her friends, and listen to loud edgy rock music on itunes) for hours on end. She thoroughly enjoys friends and any outings with them. Is she skipping any desirable phase of growing up by brushing aside any desire for adventure, for the big and disruptive and unexpected? (That sounds more like an earthquake -- which I guess is what many adventures feel like at the time....)
