GG's nemisis

Karen's grandma loves to repeatedly shared a story about Karen when she was little. The story goes that Karen's grandparents were away on vacation and while they were gone the Folger's came to visit and rake leaves, clean up the yard, etc. Karen's mom didn't want them to know who had been there so she made sure she cleaned up after all of the kids. When Grandma and Grandpap arrived home, they knew instantly that Karen had been there. How did they know??? Because Grandma found petals plucked off of her plants inside the house and plants pulled apart outside....

Well...the trait must be genetic...
