Create a storyboard where the image does not depend on the text and the text adds something new to the narrative. This exercise is a light-hearted look at the role of image and text. Aim for it to be around 10 frames long. Draw the picture storyboard first and then add the text. Note how the story is affected when the text is added.
Please excuse my horrific drawings.
Without text
With Text
My storyboards only changed slightly with the addition of text. The main difference between the two is that the text added an element of humour, i.e. the parents deliberately contacted the son before they returned home, in order to give him a chance to clean the house.
