I was thinking of my dad this morning, for no apparent reason, and remembered this incidence.
Dad used to breed and show canaries, infact in the 1970's one of his canaries one a world championship in Buenos Aires.
If his canaries wern't up to show standard he would sell them to people as pets.
An elderly lady came for a pet bird that would sing so he gave her a cock bird and told her that the bird would like to eat a bit of greenstuff once a week.
The lady came back a few weeks later and said the bird had died. Dad was at a loss until it turned out that a bit of greenstuff once a week was all the lady had given the bird, no seed or water.
The moral of this tale is never assume that anyone knows what they need to do.
