concept for poem

Concept- I chose this poem because me and my twin would go back and forth with each other saying it when we were younger. I took the concept of the knock knock joke in the beginning and made it literal. After that I wanted to show the argument between the two through a door. I wanted to used real people but I couldn’t get them to look right even buying masks didn’t help. So I went back to what I knew, Shel’s strength is not creating a realistic character but one children can relate to. I wanted to make a book that would be fund for kids and allow them to use their imagination to take the poem to a new level like me and my sister.
