Far Away by Carol Diggory Shields

Someone shouts in Annie's ear,
But what they're saying, she can't hear.
Buzzers buzz and school bells ring,
Annie doesn't hear a thing.
Friends can jostle, tug, and pinch,
Annie doesn't move an inch.
"Oooo, here comes a big black bug!"
Annie does not even shrug.
"Fire!" "Earthquake!" "Runaway bus!"
She remains oblivious
Until, at last, with a faraway look,
Annie smiles and shuts her book.

Found this one in I Like It Here At School by Jack Prelutsky.

Carol could have been talking about me when she wrote that poem!
