Battle-Scarred

As if a harsh harpoon were aimed at her heart,
Fired and missed, but had still left it's mark,
Scar tissue now tough, shielding the delicate part,
Transforming this good goldfish into a shark,
With words so sharp like a razor blade's bite,
Shredding anyone who dared to come near,
Swimming in dark, but always poised to fight,
Teeth and anger only camouflaging fear,
Cold water and time serving to make things worse,
Until a guppy so sweet could reverse this curse.
