Fun story - i still have the first credit account I got when I first went to college (originally cosigned by my parents with like a $400 monthly limit, eventually became solely my own and with a proper credit limit). Many years later (after getting a much better credit card that became my daily driver) I used that first card a couple of times for whatever reason and completely forgot to pay it off until six months later, when I paid it in full. That account is now still (> 8 years later) restricted with available credit of $0, but remains a favorable part of my credit score by being my oldest available credit line by many years (the non payment dings appear to have dropped off from my credit rating) ¯\_(ツ)_/¯

[edit: i just checked and that card currently has an available credit of $-0.05 which I guess means I'm giving the bank a $0.05 credit line!?]
