Imperfection
Like the lawnmowers that leave your gorgeous green lawn with knife-sharp stripes meaning you don’t really want your kids running across them, this room could have been so impressive. You could have shown it off to all your friends and family, probably not even putting furniture in the room first.
But then the stupid robot had to ruin it by sliding right through the middle of its perfect lines all the way back to its charging station. Now you’re just going to have to put a boring sofa and coffee table in there and use it as a living room, rather than as a conversation piece. How boring.
