ellisbell what is your line of work?
Unfortunately, when your line of work is children, it isn't always that simple.
Especially when...
a child (6) has phoned the police the night before to report his dad for attacking his mum,
a child (6) arrives at school not having eaten because mum's in bed drunk and they got themselves to school,
mum is 'working' from home and the child (9) is in the house at the time - fully aware of what is going on,
one parent has been left severely disabled following an accident and their child (4) is having to come to terms with it,
a parent picks the child (4) up from school and instead of greeting with "hi sweetheart have you had a lovely day. Oh is that a picture for mummy? Isn't it lovely" is greeted with "'ere's y' fkn cake. an' you start whinging for anything else I'll fkn smack y'".
a parent doesn't believe that their new DP was guilty of child abuse, even though they served a prison sentence for it until they had proof of partners said predilection - and then one day their DD (7) stayed in at playtime to tell the teacher something.
These are all real experiences from my personal and professional life and often mean that the child rarely, if ever, arrives with the right behavioural attitude and social abilities to learn.
