"...The world's round - I mean, round like a ball, not like a table."
"Our world is," said Edmund. "But is this?"
"Do you mean to say," asked Caspian, "that you three come from a round world (round like a ball) and you've never told me! It's really too bad of you. Because we have fairy-tales in which there are round worlds and I always loved them. I never believed there were any real ones. But I've always wished there were and I've always longed to live in one. Oh, I'd give anything - I wonder why you can get into our world and we never get into yours? If only I had the chance! It must be exciting to live on a thing like a ball....."

A new perspective makes life more interesting, don't you think?
