MR ANDREW BARRETT the formidable gym teacher, is always on hand if the kids get out of line as most of them are, rightly, scared of him. He has never had any other job than being a PE Teacher and is institutionalised. The only year he spent outside of a school was when he went on a gap year to Africa. To build a school. He takes PE very seriously and will not stand for anyone bunking off his lesson – with a particular dislike of obese kids, Mr Barrett doesn’t believe there’s any cause for it other than greed. He’s obsessed with his mother, who calls him most days. He’ll often bring her up in class, as an example of a perfect woman.
