Beautiful song, Dan- and John, the photos are beautifully placed.
As for 'leaving' on Mothering Sunday', I have my own thoughts on that. It has happened quite frequently, both in my own life and in the lives of others, that there has been a climactic end on a significant day, so much so that it is my suspicion that somehow it is significant. Perhaps I am correct in believing that we all get to choose- on some subliminal level - the day and manner of our death.
That is what I choose to believe, anyway. So I would say: Cherish the day and the thought behind it.
