Oh Lulu! you have my total sympathy and understanding. Our once sweet and agreeabe DD has also morphed into a similar creature as your DD. However at least it has never occured to her to demand the CentreLink payments that we get for her.... sheesh!!!! Does any child ever really get them??? Our DD is fully aware that every cent from Centrelink goes straight into her education.... and now that she has decided that she wants to stay at her school there is no pushing boundaries where money is concerned ('cos it costs a bloody fortune!). I would maybe find out how many kids her age actually do get CL payments.... and how many actually have to pay their parents (if they have a job). When my DD was modelling she only saw about 10% of it.... the rest went into paying for her living expenses.

Hold tight to your sanity Lulu... "This Too Shall Pass!"
