MacKenzie,â I say clearly.
He shuffles through the papers on his desk, his fingertips skimming the surface.
âMargaret MacKenzie?â he asks.
âNot Margaret,â I correct him. âMaggie.â
âIâm Mr. Carlson, Maggie. Welcome to biology. If you take your seat, Iâll explain all about Scout and his job.â
This dog does not look like heâs working. Heâs lying around, waiting for something fun to happen. Mr. Carlson is busy collecting some papers, so I sneak in one more pat on Scoutâs head before I stand up.
âWhat is his job, exactly?â I ask.
Mr. Carlson puts the papers down. âHeâs a guide dog,â he answers. âMy guide dog.â He looks up at me. âIâm blind.â
Blind? How can a teacher be blind? Iâm still in a daze as I take my seat. Did he say just what I thought he said?
The other kids in the class are all exchanging glances. They look just as confused as I am. Scout watches the door as the last stragglers hurry in. His ears perk up as the bell rings. Itâs time for class to begin.
The science classroom is like the other rooms Iâve seen today, longer than it is wide, the far wall filled with windows. What sets it apart is the collection of cages crowded on the broad counter below the windows. The cages contain all kinds of small animals: mice, gerbils, hamsters, guinea pigs, and a large rabbit. As the rabbit hops from one end of its cage to the other, Scout watches it eagerly. I wonder what heâs thinking.
Mr. Carlson stands up and walks around to the front of his desk, his fingertips gently brushing against the side of it. He looks out over the classroom. No, wait. He canât be looking, can he?
Scout starts to stand up, his eyes on his companion. He looks anxious, as if heâs waiting for a command. But he doesnât get one. Mr. Carlson leans against the front of the desk and crosses his arms over his chest. Scout makes a small whining noise, but he lies back down and rests his head on his front paws.
âAs you might have guessed, Iâm your teacher, Mr. Carlson, and this is seventh-grade scienceâbiology. Biology is the cool science, the study of living things. Weâre going to study cells, body parts, worms, rats...youâre going to love it.â
I already do! A class with a dog? Iâm in heaven âwell, as close to heaven as you can get in school.
Mr. Carlson continues. âIâve taught seventh-grade science for ten years. Middle-school students are the best. Youâre energetic, youâre curious, and you tie your shoes by yourselves.â
That gets a few giggles. Mr. Carlson smiles and relaxes a little.
âNow, let me talk about the whole blindness thing.â
The giggles stop.
âTwo years ago, I developed a condition called retinitis pigmentosa. Most people call it RP. RP made me blind. I canât see you.â
âI took last year off from teaching and went to a special school. I learned how to read Braille, a code that uses raised dots, and lots of other things that help me get around. It was hard, but I made it. Today is my first day back in the classroom.â
He stops and takes a deep breath. The class is silent.
âI am a teacher who is blind, a very good teacher. Iâll use my computer a lot. It has a special program on it that reads text out loud. Anything you can read on a computer screen, I can hear. Sometimes Iâll ask you to help me by writing on the blackboard. And if anyone is planning to cheatâdonât. Iâm blind, not stupid.â
The class groans a bit. Mr. Carlson smiles.
âNow, a few class rules. Donât raise your hand. I wonât call on you.â
A couple of kids laugh at that.
âIf you have a question, just askâquietly, not at the top of your lungs. My ears work fine. Iâll hold a meeting for parents next week. I suspect your folks are going to have a few
