Out of the blue

Derek writes:

Seven & Six years ago we had a German student Simon living and working with us here at Courtlands Nurseries.
He was a wonderful breath of fresh air and restored my faith in young people.
He was engaging, hard working, used his initiative, adventurous and a pleasure to host. We then heard nothing from him but remarked that one day he will turn up “ Out of the Blue “. That day was last Friday when he arrived with his girlfriend Lucy in a camper van en route to a family wedding in Surrey. Who knows when we might see them again !
