Help! My two year old sister!?

Hi my two year old sister loves me to bits and I love her but just after Christmas she took my bracelet. I was lying on the lounge and she came up and snacked my bracelet (which was off at the time) and I said give that back and she said no and ran off. She usually brings it back but this time she didn't! I have asked her so many times where did u but my bracelet and she all ways says umm fink its in my cot of under mums bed or in your room. But when I look there isn't anything there? :S where would a two year old but a bracelet?
