If you allow your own perceptions to be swayed by a media in the business of making a profit by selling shocking stories the problem lies with you.
Maybe instead you could spend some time thinking about the people you actually meet and pass by every day. Yes there are a few unpleasant people, yes some young people are rowdy on buses, yes their behaviour can be irritating (as can adults). But how many happy children do you see playing in parks, behaving well in supermarkets (but you only noticed the one that screams), how many young people spend their time learning to dance, to play sport, to write music? How many look after their parents, their ill siblings, visit their grandparents?
@Jayne Walker I don't know in what capacity you work with children but I hope its not one that has any influence on their future life because thats a pretty disgusting attitude to have if you do. I look forward to the future with interest and have absolute faith that children and young people today will do a far better job of running society than this or any previous generations.
