I have wet my seat at this thread.!
I had a beloved goldfish called Robert, but I had to keep him on top of the wardrobe (as we had several cats). Unfortunately, though I loved Robert dearly, I only loved him dearly when i could actually see him...
I think you can guess where this is going.
Anyhoo, some time later I had a friend round to play and she glimpsed the edge of the bowl on top of the wardrobe and pulled a chair over to take a look.
''Oooh she said, why have you got a white fluffy ball in a bowl up here?''
Hem hem, the water had all evaporated, leaving the white spore covered bloated corpse of the Very Late Robert resembling a fluffy golf ball.
I was too absorbed in Sindy dolls to stop her reaching into the bowl to get a hold of fluffy object...She's probably still in therapy.
I went on to have Robert the 2nd, 3rd and 4th before my mother decided that a more Interactive Pet and Visible pet might be better for someone with a bad memory like mine.
