The Big Bear and Little Mouse were what you call  ‘Best of Friends’.
When Little Mouse would trip, Big Bear would giggle, pick him up and gently place him back on track.

When Little Mouse would fall, Big Bear would laugh, carefully lift him up, dust him off, and patiently put him back on the path.

One day, Little Mouse got stuck trying to get some cheese. Big Bear, thought it was hilarious. He pulled him out. Licked his sore. Gave him a pat and set him down to eat.

Big Bear and Little Mouse were the best of friends. Till one day, Little Mouse was sick and tired of Big Bear always laughing at him.

And left.
