We don't have a washing machine, there's a communal laundromat in the basement of the apartment complex (we're on the 3rd floor, as an aside). Each wash or dry cycle (on the machines that actually work) is I think somewhere around $3, payable only via a special charge-card that can only be loaded up using cash handed to the superintendent on one of the days when he's around and has time to process the transaction (generally needs to be arranged ahead of time). They're industrial size though, so you can fit a remarkable amount of clothes in there, and we need to use two anyways because of lights/colors.
I actually did make the mistake of mentioning that I was running out of clean clothes once, a year or two ago. "Why don't you just do it if you need it right away?" was the response, despite having been shown the workings of the machines a whole once back in the beginning of our living together, and also the fact that I don't have the card. And fuck if I know all of the settings that her clothes need.
I'm going to assume that the card exists somewhere in the apartment rather than being on her person at all times, but I legitimately don't know. I suppose I could look for it when she's not here, as she hates it when I go looking for things and don't immediately find the thing... "Why don't you just ask me?", but whenever I ask she rolls her eyes at me for not knowing where whatever it is obviously resides.
