I told them to stay home!
They just wouldn't listen. But one can never fight with a stubborn lion and one just as majestic rhino. They just settled their mind to go ahead and cross the distances in a colossal effort to witness the northern lights. In their journey they even inhaled the mountain spirit that offers them a new understanding of the world.
But just wait until they reach their destination! I bet the rhino will cry first and only then will the pompous lion start whining like a cub when the green night sky starts to resonate with their softer side.
