Found my vibrator in my younger sisters room???

So today I was having a wee look in my sisters room for some of my clothes "as she likes to take them all the time" she's 16 so its normal for her to be taking my makeup/clothes etc but as I was looking I found my vibrator hiding under her bed?? I double checked the place I last had it and it wasn't there, so I knew it was mine! but why would she take it? can anyone give me insight on it or make me feel better as I can't look at her in the same way again?😂
