The all powerful bandaid

V took A1 to the nature museum and A1 managed to scrape her right hand. V convinced her to put on a bandaid against her assurances that she was fine. Once the bandaid was on, however, A1 treated the hand like it was fractured. She ate with her left hand, refused to let either of us even touch her right hand and held it in one position as though it was in a splint. Two baths later the bandaid came off and V offered to put another one on, which A1 refused outright. To convince her that it wouldn't hurt, V put the band aid on her left hand and oh look the right hand is all fine ... buuuuut... the left hand is now the unusable one. As long as the band aid remained on, A1 refused to use her left hand... the right, the one with the scrape...no problem
