Our oldest came home from school for the weekend and took gobs of pictures and little movies of her baby brother. . . then posted them all on Facebook for her 500 "friends" to see.   So I wrote her an email trying to be as lo-key and non-accusatory as possible, highlighting privacy issues and fears, and ending up with an "I know if you had known all this you would have taken care of it already". Sent a copy to her dad, and waited for the backlash that inevitably was to follow. Amazingly - I got an e-mail back saying no problem, she would take care of it right away. I could not believe - had to re-read it 3 times - no fuss, no bother. I guess she's maturing at last!

Needless to say, I'm having a wonderful afternoon. 

Anyone with teenagers will understand.
