Yeah he is making it sound like a suggestion or an option - but in reality its an ultimatum. Either GTFO on Mondays and Tuesdays or find another place to rent.

Apparently me sitting in my room (always with headphones on) at the opposite end of the apartment and only coming out to get food is a burden that prevents him from functioning. His suggestion was for me to drive down to my parents (who live 40km away).

A yeah mate, let me drive 160km two days of the week while paying rent so you can have the house to yourself for a few hours?

Also worth noting that none of the big software companies issued 'return-to-office' and have not to this date!
I spoke about this with him in person and it seemed like this was a totally normal request from his perspective. He also had a problem when I described it as "I need to get out for a few hours."; Such phrasing was not welcomed by him. (Bruh, no matter how you put it, that's what you are asking me to do)
I ended up asking him for a rent discount when I told him that I would need about twenty euro for there-and-back trip, he gave me a fifty euro discount for the month's rent. (quick math: assuming four sets of M+T, we get 160 euro for a month, he is 110 euro short there) gg. I asked my mom if they had any room for me and in a few days I was out of there.
He ended up taking two thirds of my deposit as well. For paint that he used after mold appeared in winter and a cleaner that came in (a month after I moved out so how the hell does a cleaner service benefit me?); The room was spotless after I moved out.
I wouldn't be as mad, but its the hypocrisy made me fume. His issue with me being there was a matter of convenience, yes?

He would constantly wake up in early hours of the morning (4am, 5am, 6am) and take showers - (his shower was right behind the wall where my bed was), slam doors, when my alarm clock is set for 8am.
 Leaving dishes in the sink for WEEKS. Using the washing machine constantly and always leaving his stuff in there.

He would throw in his towel in there and not wash it for an entire week. Basically using the machine as his personal laundry bin. This was not a one-off thing either, this was consistent for the two years that I lived there.
He told me to always lock the door after I leave, but he would constantly leave it open, I'm not joking - the dude never locks the front door at night.

Constantly leaving lights on everywhere. He would turn the light on in the kitchen and then leave to walk his dog. WTF is the point of having the light on in the kitchen?! If I had rice or w/e on the stove, he would turn the light on in the kitchen even if I had it off. Like food doesn't get cooked while in the dark...

When I first moved in, I made the mistake of leaving my detergent and softener under the kitchen sink. Since he uses the washing machine at least once a day, a week later I had to wash my clothes with the few drops that he left for me and he cheekily diluted it with water to make it look like there was more in there. Like I wouldn't notice that the viscous purple gel now flows like water. The softener was half gone. Prick. It takes me about three or four months to go through an entire bottle. From then on, I stored everything in my room. Even my kitchen towel - which he would wash after one or two uses! Same with trash bags.

 I once lined the garbage bin with a bag. Threw out a few things. I come back a day later and the thing is full of his trash. FULL. And he left it like that for me to throw out. After that, I got my own bin and kept it in my room.

Can't wait to move into my own house after that.
