How would someone self-harm without anyone noticing? Including the places on their body they could do this or ways they could do this. I’M NOT ASKING for ME— this is a hypothetical question I’ll use to write a short story.

Well there are a lot of places to do it that people will have a hard time noticing. These places include theighs, stomach, chest, shoulders and even head if you part your hair. Also me personally sometimes I just do 1 singular not deep cut somewhere visible that has an easy excuse like, I fell or my cat scratched me. Good luck on your story :))
