The People Next Door

Budd and Shirlee were the neighbors of Lily and her husband Roy, (The Riordans) and of the Jensens. The couple leaves the neighborhood and Lily does not manage to live her life as she did until then, spends most of the night thinking something would happen, as time goes by, their children grow up, their son Roy jr. moves out with his girlfriend, and Sara becomes a Psychologist.

Theories about the missing couple were the trending topic in the neighborhood, Lily has plenty of her own and she can't stop thinking about the house, she hears voices during the night. Twenty years after the family left the house she decides to go inside and make sure it is empty.

I would give a more intriging end to the story, did not like very much the original one, so:

I go inside through the window, into a big room with a kitchen and a living room, it looks tidy but the fridge. I leave the room and go into the dining room, there is a half-eaten dinner, the glasses have a strange tone, by the smell I preffer to stay as far away as possible from it, apart from the dining table there is nothing else interesting on the first floor.
I climb the stairs, walk through a thin hallway, I skim the bathroom, but it is wet and all covered with a thick layer of moss, the mirror only shows green, so I decide to check their bedroom.

The room is a mess, the bed is unmade, there are uncountable things on the floor. There is a desk with a lot of papers and a pencil on top, the sheets were torn, and a few are crumpled, as I get closer to read them I feel like somebody follows me, but I can't hear anything, I read and start shivering, the paper had somthing handwritten in it, and only the last line was legible:
'...finally, she felt our pressence as she takes the paper.'
And the rest of the sheet is blank.
