smurf: Why has she become like that? and what is the solution?WOW!!.. That is quite a situation you have here.Anyway, I think that something must have triggered the sudden change of behaviour in your friend's daughter. It has already come to a point where her parents are losing control over her. Personally I dont think thatusing physical force works on her. She may see it as a reason to \"rebel\" further by doing worse things to hurt the parents.I would suggest for her parents to speak to a counsellor from their Church or their daughter's school about the problems faced. Let the counsellor know about their discoveries ie; tattoos, piercing, blog comments etc. From there, the counsellor should be able to roughly gauge how best to approach the situation. However, the counsellor cant work miracles as it will take some timeto get through to the other party depending on how receptive he/she is to counselling. Should counselling fail and if matters really get out of hand (God Forbid), then I guess her parents has got to make a decision whether or not to make a complaint against their daughter.Just a point to note, blogging is one of the ways for someone to express their feelings. There may be some clues as to why your friend's daughter is behaving in that manner which could be mentioned in her blog. However, I personally DO NOT condone blogging especially among teens as many of them may be exposed to a lot of wrong influence and may be too immature to handle them. Sad to say that there are a lot of \"predators\" lurking in the blogging community who prey on these naiveteens.Thank goodness, the government realises this worrying trend and that is why there was a recent amendment to the law which now includes \"Sexual Grooming\" as one of the offences to deal with such predators who entice children & teens over the web.
