- Sirius doesn't have a house, he has a Nest(TM)
- Snape finds this out the hard way one day
- "Sirius what the hell this is disgusting"
- "Says the one who washes his hair maybe once a week"
- Snape ignores him and just starts picking things up off the floor
- Sirius eventually gives up and starts organizing, but he's complaining the whole time because "he knows where everything is, he doesn't need to clean"
- Eventually the area looks... presentable
- But as soon as Snape leaves, Sirius is making a mess again, like how dogs immediately go and roll in something after a bath
