I read my sisters browsing history
are you just curious or you're hoping to find something?
I just want to know what she does online all the time.
Even though she's your sister, you have no right to check her online history. You should respect her privacy.
You are such a drag. Not like I found anything interesting anyhow.
That's not the point. Doing this is an invasion of her privacy. How would you like it if she or someone else snooped on what you do behind your back?
