Agree with the lack of good role models. This is particularly true of some boys who feel that being a lad is what being a man is all about.
I would also put forward the following for some kids.
Lack of respect for the views of others.
Lack of respect for those who seek to help them, parents, teachers police, medics etc.
Lack of dicipline, parents are now often running scared of their kids, afraid to lay down the law because the kids will not like it. Well, tough shit, sez I.
Lack of any real consequnces of poor behaviour. I'm sick of controling classes by sheer will power and 'bluff' If kids arse around they need to hae real sanctions.
Lack of any will to do things for themselves , or to make life better for themselves and others around them.
Lack of the chance to still be kids, they are sexualised way too young, they would be better doing semi structured activites that allow them still be be kids, and to mature in slower time.
They have the mistaken idea that they are the equals of adults. They are not. They should be treated politly, but we treat them as adults at our, and their peril. They are not adults, they are teeagers and still need guidance and control, from adults who love and value them.
