They are. I have two children, moved around, been to lots of schools. They are always there. They turned up last night to pre-school parents evening.
Child: stunningly beautiful, trendily dressed, appallingly behaved, can't read.
Mum: Used to model, tall and blonde, dresses like a pole dancer, ignores child.
Dad: Surfer shorts, Blackberry, longish hair, dabbles in property/import-export.
AND, by the time the child leaves school this has always happened:
House repossessed
Dad has affair/tax investigation
Child goes to Art School.
