You’re wondering about the somewhat unsteadily drawn line down the middle of the room?? Well, one day, old FairyChatMom - she’s the one in the ratty housecoat and worn-down slippers - got into a bit of a tiff with one of the other residents. She found a permanent marker and drew the line, declaring that her adversary was not to come on her side. Oddly enough, she can’t seem to remember which side is supposed to be hers, nor can she remember who she argued with or why.
Anyway, you can get on her good side by offering her chocolates - especially if they’re the good kind and not the cheap, waxy generic stuff. Just be sure to remind her to put in her teeth before eating them.
