oxo, with hindsight do you wish you had monitored his usage a bit more closely before it got to that stage?
you see, I don't read everything my dd does, its more like an occasional nosy at the tone of stuff, and to see if, on the whole, she is being truthful about who she is with and where she goes
it has a downside of course, when I find things like "I fucking hate my mum" etc but I would never pull her up on anything, more use any info to "guide" a discussion or veto a trip somewhere
eg. I know she is coming under a lot of pressure to go to the nearest big town with some undesirables
at the moment, she is allowed to the nearset "small" town with friends that I know
on MSN, I found some "well, tell your mum you are going to X, and we will do Y"
I also discovered some "I'll tell my mum I am sleeping at yours, you tell yours you are sleeping at mine and we will stay out all night"
so, I found another reason why she couldn't go out those times and, at an opportune moment, had the "truth, honesty and freedom" chat
sometimes, I think teenagers want you to rescue them from these situations, just like your ds did oxo
