I have one housemate amongst others and one time , I saw he put his shoes away near the common area/wall/side but one was out of line or in the middle of the hall: https://imgur.com/a/a8SwkGs

I texted him and asked him to move it: “Whose shoes are these”

and he did

A 2nd time 3 weeks later, I texted him to come and put his shoes/slippers on the side and said they were in the way and he fixed it: Can please you come move your shoes. They are in the way

3 weeks later , one of his shoes soles was on top of on one of mine which I just cleaned: https://imgur.com/a/XVzdYdy

and I took a photo and sent him a message saying I won’t ask again and keep his shoes in order and told him to come fix it up now and I’m not going to do so: “Hey! I’m not going to ask again. Can you please put your shoes in order? Come up and do this now. I’m not going to move it. If you can’t keep them in order put them in your room”

He did but then said he’d be more mindful but asked me not to order or demand him to do something so small/trivial such as this and all cuz I was doing something.

I said I have the right to as I asked him nicely before and its about my stuff and its his responsibility to make sure its not damaged or something and said if somethings is in my way or ruining my stuff, I’m going to demand and order to it to be done right away. I said I was sorry for disturbing him and I’d rather not do so and I won’t if he keep his shoes in order.

I hope he doesn’t do it again but what can I do to ensure?
