A lesson in life
The other thing with the fish is that we enter into the territory of pet care as lesson in life stuff. So we have learnt all about responsibility, care of living creatures, becoming attached, dealing with illness, facing the possibility of losing someone/thing that you love, and perhaps even facing the very scary subject of death. We have really been thinking hard about these issues and learning lots about them.
The kids, on the other hand, don’t give a fuck.
