The Seagull and the Barnacle

The Seagull and the Barnacle are good friends even though they're very different. The Seagull flies over the ocean to wonderful places that the Barnacle can't even imagine, because he's spent his whole life stuck on a rock. When the Seagull tells the Barnacle about his adventures, does it make the Barnacle feel jealous, or sad? Or is the Barnacle happy, in his own way? Maybe there is enough beauty even in one small corner of this world to fill a whole life - but maybe it takes a barnacle to know it.
