RE: Find a letter...in your teenagers pocket, would you read it?
I would not read the letter, and I would take it to my daughter and give it to her, telling her I had found it in her pocket, had respected her privacy, but was honestly very curious. I would tell her that I didn't want to read it, but would voice my concerns about her boyfriend. In other words, I would use the unread letter as a stepping stone to bring up another topic that I did want to discuss, and to show my daughter that while I was very curious about her life, I respected her privacy. I'd leave it with, "if you want to talk about anything, let me know". Oh, and if I suspected the letter was from her boyfriend, and that he was trying to get her to have sex, I'd bring that up, too...maybe not at the same time I gave the letter back, but soon thereafter.
