She hurt me.

A rusty kitchen knife dropping accidentally into deep scar tissue; ripping open a flesh that remembered an age old pain. An innocuous surface earthquake; well placed, and soon cracks appear at the bottom of a long extinct volcano and lets a sulphuric emulsion of nefarious gases and blazing lava infiltrate to the surface.

Should I go to her an inform her that her careless words were hurtful? Or do I gnaw on my ire alone and accept that I am the only one to be concerned with my sensitivity?
