''I remember my first day at school waiting in the office and I was so nervous. You welcomed me in the first instance. I remember walking up the hill next to you after you had a bad day at school. Although we didn't really know each other, I have always remembered you and your face. Fly high you beautiful soul. You will be missed,'' a former Kaikorai Valley College pupil posted.
Another wrote: ''You were one of the most kind hearted and genuine people that I ever had the pleasure of meeting. You always put the needs of others in front of your own and you never had a bad thing to say about anyone. Thank you for making school that little more enjoyable!
