The Proverbial Has Hit The Fan

Lauren isn't here this morning =( she ending up going to my parents yesterday with an overnight bag - i'd had enough! her behaviour has been awful lately and if she is now showing her true personality then its not a very pleasant one at all =(( she seems to think the world revolves around her, maybe even owes her something, and doesn't care who she annoys or upsets along the way as long as she is getting to do what she wants to do at any given time. i've tried reasoning, explaining, listening but with each 'occurence' she seems a further away from me =(( i understand being a kids difficult... but only if you make it difficult, surely? ...and she's 11.. and missing out on so much... i question my parenting abilities because i must have done something wrong :/
