When I’m asked to name my favourite teacher, I immediately think of Mr Sweeney. In his class, Mr Sweeney taught us all about architecture he had the class start by learning to measure things very accurately. We studied environmentally friendly building methods, and we designed and built our own homes of the future. Mr Sweeney was always fun and interesting, he believed that we could do more than we thought we could do. He helped me break boundaries in my life, he was a positive influence on me and will always be one of the most inspirational people in my life.
