After years of being afraid of most things as a wee child, these days it's almost the opposite, but sharks have always terrified me. Maybe it was "Jaws".
I choose to place children or babies in the midst of 'terrifying' or adult situations to uncover an interesting juxtaposition. In this case, the goldfish is the protector, the warm blanket, the fearless swimmer, the sentinel and there is no reason to be afraid. I recently swam with sharks and kept calm and true like the child and this goldfish.
