Here we go.
the house repainted biannually to give the appearance of occupancy.
Who repaints their house every 6 months? A good coat of paint lasts for decades.
SCP-2257 is a white, one bedroom, two bathroom home in a suburban development located in ██████, Wisconsin. The exterior presents no anomalous properties. The interior is normally furnished for a suburban home, albeit that only one occurrence of any object, such as an armchair, exists within it.
The house in the picture isn't white, it's tan, and peach colored.
The statement "albeit that only one occurrence of any object, such as an armchair, exists within it." Feels like a tone break to explain that only one item of furniture of each type is present on the premises.
instances of SCP-2257-1 become agitated until they are able to return to the formal cutlery arrangement by dining standards in the United States of America (the salad fork must be on the far left, the dinner fork beside it, etc).
Dining standards? Is there such a thing?
All instances of SCP-2257-1 are capable of rearranging themselves when left unobserved. When objects and entities enter SCP-2257 that are not currently an instance of SCP-2257-1 enter the premises, instances will try to deter the subject from remaining within the home until the 48-hour threshold has passed, at which point the new instance is welcomed, so long as another occurrence of the same object does not already exist. Instances of SCP-2257-1 will rearrange themselves in ineffectual attempts to menace or otherwise deter objects that are deemed useless or extraneous.
But you said there aren't any living instances, how do we know they would be welcomed? Also how does one menace inanimate objects? If we drop a coffee maker in there, how could it be intimidated into leaving? It's a coffee maker!
Closing Statement: Interviewer rose from SCP-2257-1-23 without incident. SCP-2257-1-23 continues on a rant to attempt to draw interviewer back to it, but fails to convince Doctor B█████. The chair is reported to be comfortable, but not extraordinarily so, defined when off-site as an average armchair.
I thought entrants were deterred from staying. Also I got a good laugh out of that interview log. "I Bless your leavings!"
The conversion a living entity into an instance under SCP-2257 was previously presumed impossible. However, on 2/25/2014, SCP-2257-2 was created. SCP-2257-2 is a former D-Class, now referred to by other instances of SCP-2257-1 as "The Guardian", and is the result of a need to replace recording equipment continually converting into instances of SCP-2257-1. Conversion occurred unexpectedly after normal 48-hour threshold.
I would consider the fact that a living instance was created to be important enough to mention in the description, yet you put it waaaaaaaaay down here under 2 interview logs. It might alleviate things if you put the logs under collapsibles so we could see it or at the very least include a see addendum (insert addendum here) int he description.
Doctor B█████: Who are you? SCP-2257-2: The Gatekeeper.
I'm sorry…just…I'm sorry I can't help but think of ghostbusters.
In summation, it's mostly good, but has some annoying inconsistencies. I do like how the objects inside act all petty and the bit about the level 3 badge trying to be too big for his britches was funny.
Fix these and You got my upvote.
