The Bat and the Weasels
The bat asked the weasels to play, but they refused because they thought the bat wasn't a "real" animal. After a storm, the weasels sought refuge with the bat and learned to be kind and not judge others based on their appearance.

Once upon a time, a bat named Bob inhabited a small cave deep within the woods. The bat took to the air one day and went for a tour of the woodland. While in the air, he witnessed a bunch of weasels having a blast and engaging in playful activity.
The bat had this thought: "The weasels obviously enjoy themselves. Please include me in this!" To find out if the weasels would let him play with them, he flew down and approached them.
The weasels took one look at the bat and scoffed. "There's no reason for us to use a bat in our games. Not even close to being an animal, "as they put it
The sad bat couldn't take it. It was the first time anyone had ever treated him like this, and he was at a loss for what to do. Sad and lonely, he flew back to his cave and sat there by himself.
The weasels kept having fun, but the bat was left behind and stayed in his cave, feeling sad and lonely. One day, though, a terrible storm swept over the woods. Trees were uprooted and weasels' dens were blown away by the gale-force winds.
Weasels trembled with fear and had nowhere to run. They recalled the bat and his safe haven, and they hurried to beg for refuge from him.
The bat gladly welcomed the weasels into his cave so that he could help out his pals. The bat had saved their lives, so they cuddled together and rode out the storm.
As soon as the storm passed, the weasels went to make amends with the bat for their treatment of him during the ordeal. They admitted their error, saying, "We were wrong to exclude you and make fun of you." We are truly sorry and know you are a loyal buddy.
Since the bat had forgiven the weasels, they were able to spend the rest of their days enjoying each other's company and playing together.
The lesson to be learned from this anecdote is to treat others with kindness and respect regardless of how they look. You can never predict when you'll need their assistance or when they'll do something incredibly kind for you.
