hypothetical, of course
Suppose you have a daughter. Let’s say she’s 13. Further, let’s suppose that she has a blog.
Say this daughter has been increasingly sullen and petulant as of late. Oh, and she came out of the bathroom Monday morning wearing black eye shadow and black lipstick.
You happen to read her blog one day and discover that not only is she cursing like a drunken sailor (no offense to drunken sailors, of course), but she is being incredibly rude and disrespectful towards family members and family rules. In short, her blog certainly does not reflect the way that you raised her and you are so disappointed in her that you feel like throwing up.
a) Confront her with a printed copy of the specific entry and tell her you want to talk about it, knowing full that she will probably move her blog to another location and thus end your chances of knowing what she’s up to, or
b) Hope that she was just showing off for her friends and she really doesn't talk like that in public and she was just exaggerating on the other stuff, or
c) Say nothing to her about but secretly seethe.
[Also keep in mind that in this hypothetical situation, you are concerned that she is being unduly influenced by friends, have said as much to her, but were met with a glare and a stamp of the foot and a declaration that she will never stop hanging out with those friends, even though she has another set of friends that are respectful and studious and just...nice.]
Hypothetically speaking, of course.
