Say you are writing a letter - "Hey Bob, well you know how we are going on a holiday... I do not want to go. You talk loudly, pull my hair - so I wanted to say goodbye." This poem says that in a more artistic, and less harsh way.
Oh Bob, I think we're in a blob!
You know about the holiday, I think of saying nay.
You always pull my hair, and sound just like a screeching chair!
I want to say goodbye, so go fly in the sky .
