Notice the quotation marks on the last line. It helps to understand the joke if you read it out loud and do the quotation hand gestures when you read it.
You were my everlasting delight,
You filled me with joy;
Always dressed in white
So was I just a toy?
You danced in your white dress
Before you started these affairs
You dance in your red dress;
“She fell down the stairs.”
Due to its short length, I posted this as an Addventure so that you, the people, can feel free to voice and add some lines leave the original poem alone, but copy it to a branch, then add your own text.
