How to give Katherine a cosmic meltdown:
Me: Is this your toothbrush on the left side of the sink in your bathroom?
Kat: Nope. Must be Jeffrey's. Mine is the purple one on the right.
Me: Jeffrey, is this YOUR toothbrush on the left side of the sink in your bathroom?
Jeffrey: Nope mine is the purple one on right
.
Kat (rushing out of her room): WAIT.... WHAT????? NOOOOOOOO!!! That's MINE!!! OMG OMG Have YOU been using MY toothbrush all this time??? OMG OMG That is SO gross.... YUCK YUCK YUCK.... MOM I NEED A NEW TOOTHBRUSH.... EW EW EW EW..... I'm just going to die. That's it. Life is over.
She ran into her room, choking and gagging and slammed the door.
At least I now know why the toothbrush on the left never looked used.
