<human>: Tonight, I[19/f] noticed a welcome back to Facebook notification in my inbox dated a week ago. I had 3 unread messages before I deactivated my account, now they show up as read. I realized it was my mom[55] because no one knows my password, but it was saved onto my computer. My mom asked to borrow my password protected computer last week while I was in class. She deleted all of her fb escapades from my history so she must have known it was wrong. She admitted to logging on to and reactivating my Facebook, but denied reading my messages. She gave me the if you have nothing to hide you shouldn't be upset excuse. I don't know how to argue against this without revealing why it upset me so much. I don't know how much she read. The thing is I don't have anything on my account that even she would consider bad, but I sent very private messages to my old roommate's account after she died. I feel so sad that my mom might have read them. I'm so sad.

Provide a brief overview of the text.
<bot>: How do I respond to the "if you have nothing to hide you have nothing to fear" argument without revealing the thing that I am trying to hide?
