Tonight After Work It Was Raining

I went into Grandma and Grandpa Spiehs' house and went to wake up Sleeping Beauty Isaak. He usually is awake, but doesn't want to get out of the bed he sleeps in.

I said to Isaak, "Come on lets go! It's raining cats and dogs outside!" He sort of got ready once I told him it was raining.

He told me minutes later, "Come on lets leave! I want to see the raining cats and dogs!"

I had to break it to him that, "It's raining cats and dogs" is just a saying. Then went on to say it's just raining. There are no dogs and cats to see. He looked so confused.
