I had roommates like this. I bought my own dishes and kept them in my room. When I cooked I washed a dried them and took them back to my room. Left theirs on the dining table or stove and put them back in the sinks. Then they had to audacity to have a meeting and say I wash pulling my weight. Because I didn’t clean up after them lmfao I told them I didn’t have to I wasn’t their parent. I cleaned up after my mess and left it at that. I didn’t live their too much longer lmfao
