It isn't weird at all, its just theres very few of them. When I was in Year 6, my teacher went on maternity leave, and we were replaced with a male teacher. He was fantastic. Only young, straight out of his degree, but he really knew his stuff. He knew how to keep the class entertained, and yet still made us all stride to work our hardest. In fact he was probably the best primary school teacher that we ever had!
