My roommate stopped me from doing laundry when I came home at 7 PM because he said he was getting ready to do his first. By stop, I mean I was putting my clothes in the washer, and I took them out when he told me to because I wasn’t time pressed. 

I slept until 11 PM afterwards, so he could finish his laundry. When I went downstairs to start the oven, I saw that he was on the couch with a movie, so I assumed that was what he was doing during this time. But I didn’t talk to him. 

At 11, I took his wet clothes from the wash and put them in the dryer, but I didn’t turn it on because I don’t know if his wash requires something (e.g., what temp, if he uses dryer sheets). I then put my clothes in the wash.

At 11:45, I put his wet clothes from the dryer and put them on top of the dryer.

At 12:15, he took my clothes out of the dryer and blamed me for being the asshole for not communicating. He said that he was angry because my putting wet clothes in a pile on top of the dryer could lead them to sour (but didn’t address that possibility for me). And I said not only did I rearrange my schedule for you, I assumed you wouldn’t mind if you waited an hour more for your clothes because I had already waited 3 hours. I said I would’ve put them in the dryer after I was done and not started the dryer cycle for the same reasons. He said he wouldn’t have done that if he were me, but I said I would not mind.
