I would like to thank my wife, Clare, and children, Louisa, Patrick, and Isobel for their understanding and encouragement. I owe a debt of gratitude to several professional colleagues whose contributions over the years have been inspirational Jim and Anne Keogh, Sue Cocker, Ian Edwards, and Ben Lewis. The staff and pupils of St.Gabriel's have been wonderfully supportive, consistently providing invaluable feedback. Lastly, I would like to thank Sean and Josie, Mary, Ger, and Cath, my first teachers!
