Phonetics Fun

My 8 year old and I wrote this poem this morning:

Phonetic Mysteries

I don't know how, I don't know why.

I don't know why "y" is called a "y".

I don't know how, I don't know why.

Why is an "i" not a "y"?

I don't know how, I don't know why.

Why "y" is not "i" or why "hi" is not "bye"?

I don't know how, I don't know why,

but I do know that "I" am not a tie.
