Losing a pet is usually an inevitable thing, they live much shorter lives than us humans (if you didn’t already know) and it can be an extremely sad situation.
This lad knows it more than most after recently losing his goldfish, and to be fair to him, he holds it together pretty well. Until the flushing. Then he loses it.
It’s good to learn these lessons young though, he’ll be much stronger for it in the future, and now he has a little goldfish to watch over him. Well, if he ever gets out of the sewers.
