story = '''On 4/1/00, when Ashley was 10, she found a squirrel that apparently
fell down from a tree. She named him Pip.

Her furry friend recovered completely, and one day went back to the woods, with a
funny-looking chipped ear that resulted from the fall. She thought Pip was
gone forever.

Little she knew... On the day Ashley was getting married, 03/05/2015, becoming
Mrs. Goldsmith-Goldstein (so much gold), she saw a funny creature hiding in the
bushes. The chipped ear was unmistakable: he came back to say "congratulations".'''
