It Doesn't Hurt (Garycato One-Shot)

Avocato has began to notice something odd about Gary...

----------
Based on a headcanon I recently got for Gary which is "high pain tolerances" and an old headcanon where Gary tried to convince himself (in his younger years) that he wasn't feeling pain/hunger/cold because he read somewhere that you could trick your brain to do it.

Originally it was going to be a prompt- that's why it's short.
