Let's look at a very cute children's book, Open Your Eyes which was published in 1964. I bought this at a thrift store several years ago when my daughter was younger, but I like it as much as she did. The illustrations are so charming.
It is a simple story of two brothers stuck inside while it is raining. They try to think of things that are different colors. The text rhymes too.
And who doesn't like a big, smiling sun? Nothing like a happy ending.
I hope you have a sunny day!
