I love them, and I only hide them in workplace environments when I'm going to be around others who are of a higher status in the company.
Otherwise, I love just having them out, I like that people stare at me, I like that depending on the circumstance I can be labelled by others as a freak or product of misfortune, or both.
if someone is being an asshole to me, and I casually roll my sleeves up, I can watch their expression go from agression to shock/disgust/fear real quick and that makes me feel powerful in a sense. Its been years since I haven't had tons of them marring my appearance, but once I accumulated a ton of them, people who used to bully or look down on me started to feel guilty about their conduct or fear towards me, I like that. It makes me feel like I have control, and that my pain is real, which is why I got into this addiction in the first place.
