This is a fun story about a little girl named Patrice who just happens to love rainbows. She loves rainbows so much that one day she imagines herself swinging on one. "What a terrific idea," she says. She takes her kitty and goes outside to tell her friends about her wonderful idea. 

She is so excited about her idea and hopes her friends are too. Some of them are all for it, and some are a little afraid. "Because that's not why rainbows are made," they told her. Just as she's about to convince them, storm clouds come out and it starts to rain...

All of her friends begin running home, "leaving Patrice in the rain all alone." Patrice walks home, crying and feeling rejected. Upon entering her backyard, the rain stops and the sun pops out. 

Patrice can hardly believe her eyes for over her swing is the world's prettiest rainbow. "How could this be--But A Rainbow! A Rainbow! A Rainbow for me." She runs and jumps into her swing and begins SWINGING ON A RAINBOW.
