My last girlfriend didn't understand my Sandman collection, my copy of Watchmen or even my The Books of Magic stack. "Comics are for children" she cried.
I disagee, take a look at V for Vendetta for political writings, the Sandman collections for twisting, turning plotlines worthy of any novel or Watchmen for sheer fantasy.
You may still them of them as childish, but if you must try to think of them as childlike, there is a difference.
