Just moved house. 2 eldest sons insisted they shared the largest room.
I offered them the option of one having the 2nd reception room downstairs as their bedroom so everyone has their own room but they declined.
Had this discussion several times with them. Always the same, they want to share.
So, I buy a £200 table and chair set from marketplace for the dining room. Wallpaper (to my taste for a dining room, not a teen boys bedroom) accessories, a sideboard etc
They get heavy wooden, double ottoman beds built (on 3rd floor btw!) set up their drawers from flat pack, wardrobes etc.
Now weeks later they're asking can one of them move into the reception room.
AIBU to say no, because I must have asked them 10 times.
I've bought everything to do it out as a dining room now.
It would mean taking a wooden bed, wardrobe, drawers, heavy double mattress down 2 flights of stairs.
I've got enough to do.
AIBU to say you made the decision now you have to stick with it?!
