that
and what i did (when i was renting an apartment with some guys for couple of years ), was just be as careless as they were , i found out that me doing it made them just automatically leave it to me , and when i didn't do it they were surprised , so i said that i'm not the only one living at this house and established my point the hard way , which was hard because i had to leave things that needed to be done (like fixing things they broke , clean their mess , get food! ,......) and i had to live with the chaos for a fair amount of time without even trying to fix anything or get anything in order (which was sooo annoying , but eventually they started doing things on their own (at least some things)
good luck
