You decided to switch something between Vicky and Sarah.
You opted for something small and quick to notice. You were intrigued by this physical trait folder.
Flipping through folders you pick out Vicky's physical folder and Sarah's physical folder, without closing either of them (it took some doing).
Something small and noticeable... hmmm. Well, eyes were out. Vicky was asleep. You probably wouldn't be able to switch their body types without much of a change. Maybe just their faces? Well, Vicky's face was far too cute to change out.
You decided to just switch their feet around. The blanket wasn't quite long enough to cover Vicky, and you could peek over and see if she altered.
You pull out each of their feet subfolders and quickly switch them around before putting them back into their separate drawers and then closing the drawers.
Cautiously, you lean over and take a peek at Vicky's feet...
It was a success! Sarah, being so much shorter than Vicky, also had proportionally much smaller feet. She was perhaps a size 5 or 6. Vicky's former feet were size 9 last you asked. But she definitely liked to squeeze them into smaller shoes - they gave her quite the bunions. But, upon closer examination, Vicky no longer had her old bunions either! She now had some nice french tips and a toe ring.
Looks like you could switch physical traits between people. It was a plus that Sarah's feet were so cute. You were curious if Vicky or Sarah would notice the change, you hadn't altered their memories of their feet... but how often do people compare their foot size to before?
You went back to the filing cabinet, eager to explore more
