Hahaha! This happens a lot to me too (not realising that I have a cut till it starts burning). Oh, and I definitely get annoyed if I'm unable to finish tasks properly. 😂 You're a funny guy, fellow INTJ.
@Megan Ring back when I was a kid I got my ankle caught under a fence and the fence cut me open. I got up and just kept going telling everyone I was fine till they pulled me into the office. I still have a scar 😂
