Because that what everyone else does.
There are 9 pairs of shoes on the kitchen floor.
3 are D2s
1 D1s
4 Hs
There are 14 assorted jumpers, hoodies and coats in a heap in the middle of the floor. They were on chairs and end of bannister but I have gathered them and built a pyre. I shall be burning them all later.
In D2s bedroom are 4 plates a 8 damp towels. I can't even look in D1s room.
I hate them all.
