Neil's life

Personal testimony

“He was artistic. He was musical. He was a happy-go-lucky person. He was a lover of all souls.” — Sonya Muir, Neil’s daughter

In the recollections supplied from the podcast, Sonya remembers Neil visiting her every second Sunday. She recalls sitting on his shoulders, running her fingers through his fine hair and laughing with him. She describes herself as one of his priorities.

She also recalls his care for other people, including checking that a neighbour got home safely from work. Another recollection describes Neil and his close friend Dave joking about a surfboard on their car, although neither of them surfed.
