What is the Name of the Poem?

Question:

I am a 21 year old college student who used to read your Alice books ALL the time in middle school. I was sitting in my room one day thinking about the fun I had reading your books and started to think about the poem I read in “Alice In-Between.” I know that she recited the wrong poem in class and it was about her mother, but I can’t remember the name of that poem. I have searched high and low, but I have not found it. Can you help me?

The title of the poem is “Passing By,” and the author is unknown.
