BY FAR THE BEST ENGLISH TEACHER I EVER HAD. :)
Yes he is a bit mumbly but a genuinely nice teacher. I had him for advanced higher and he was nice enough.
By far my favourite teacher at the school. He helped me a lot and I'm now on my way to becoming a writer. Thank you sir.
he's very smart! but did mumble and hum to himself haha!
Mr. Callaghan is a bit of a genius, however, sometimes he thinks his class is too.
