I read on an earlier thread today that if your Google your DC you can get their Tweets up. I never realised that and so tried it and read through a few. Now I know I have invaded her privacy and I'm not happy/proud of myself but I am disturbed by one thing I read.
DD has a fascination with the Brighton clubbing scene and goes down there quite often (we live 2.5 hours away). I always ask her what her slepping arrangements are etc. She drove down several weeks ago with a friend to go to see a band on the Fri and go general clubbing on the Sat. I am ALWAYS stressing to her that she HAS to leave 12 hours between drinking her last drink and driving. When she went down this time I asked where she was staying. She told me she was staying with student friends that she met on holiday last year. Having read her tweets, it now transpires that they slept in her car!!! I am livid as we have always told her too that if she is found in her car, drunk, she will still be done for drink driving. Apart from the obvious lack of any decent sleep for two nights on top of all the alchohol and then driving back on the Sunday, I am absolutely gutted that she took that risk and lied to me about it. Should I, or how do I, tackle her about it? 
She also lost her phone in a club on the Sat and ended up with a fat lip that she said she got in a 'mosh pit' but her Tweets say this was not the case but doesn't actually say how she got it!! Help please
