I've seen people with unusually long pinky nails, and sometimes when I interact with them (like taking money from them as a cashier) they would purposefully scratch me with that long pinky nail. I know it's on purpose because they really dig in for a good long scratch, and they stare at me after, waiting for me to react. The people that have done this usually look unhappy and they wear metal t-shirts and alternative hairstyles and all that. Like they shop at Hot Topic. Nothing against emos and metal heads, but is this a thing? Why do they do it?
