ANYONE WHO HAS IPOD TOUCH?

ok i'm not sure if this is going to make sense but i'm suspecting that my sister is doing something wierd with her ipod touch. everytime i ask to borrow it she tells me to wait outside the room so she can grab it...and she doesnt want me to know where she puts it. BUT SHE STILL LETS ME BORROW IT. so y doesnt she just tell me where she puts it. i know for sure she has internet on there. but heres the question...what could she possible have on there that she doesnt want me to see and possibly gets rid of (in the time period that she grabs it for me)...please help me out with this
