This is what i hav been saying for years. We treat children like crap in this country.
Right from birth people are moaning about pushchairs on buses and babies crying in restaurants or bf in public.
Then they get older and we are slated for daring to drive them to school and they are moaned at for playing too noisily in their gardens.
Then they get to teenagers and although this country provides sod all for them to do,they are berated for hanging about on street corners or being in groups and spoken too and abouit as if they are 2nd class citizens.
Then we wonder why they disrespect adults.
I saw a woman telling a group of chatty school kids off on the bus the other day-IT WAS THE 3.30 BUS FGS.
I saw 3 nice lads order a take away from the local chinese the other day and get told to "wait for it outside" In the rain i might add.
When my lads were younger there was an anti dispertion order in our village.
I had several letters from the police that they were in "gangs"
They were walking home together,they are brothers 
The old people said they were intimidated by them although would swear at them for no reason as they passed them,one old lady even kicked my sons bike over as she walked by,it was just leaning against a post and not in her way.
I was in the park the other day and a few were a bit sweary. I asked them if they could tone it down as i had dd with me.They apologised and stopped cos i asked them nicely,had i been vile they would probably been vile back.
Hrdly rocket science.
There are a few bad apples as there are adults but untill we start to trate our childen and youth with respect this will only get worse.
