Stooping to her level is not the best way to resolve this. In fact the parents might even side with the daughter and get OP in trouble. So yeah. Just demand that she return it.
holy stuffshe didn't even take it with permission?even though she's your own sister you could probably threaten to take actual legal actionI know it sounds stupid to do it to your own flesh n' blood, but still.Tell her I said "forget you."
Speaking of which, how old is she? Her having an "office" gives the impression she's about 16-25
Tell your parents about it.Also, why didn't you stand up to her? -_-
There is nothing to stand up for, I can't just get all my stuff back
For 500 bucks I can make sure no one ever hears from her again
Then tell your parents that she took YOUR computer for HER personal use, and deleted the stuff you bought, created, and worked hard on.And tell her personally, that I told her she can go forget herself.
You know, there is this thing called revenge.
what are we, five
