Look, Nigella, I am not trying to make out your are a bad parent, we all struggle, rich or poor, to be good enough parents. Every day is a challenge and it is exhausting and demoralising as a single parent, especially for dcs with SEN, when there is not enough money to cover all the essentials and we have to pick and choose.
I was actually trying to be helpful about finding funding for the shoes. So that your DD can avoid those sanctions in school which will make her feel bad, and will lead to bad behaviour.
Its MN. People are going to disagree with you. Shouting the odds about how everyone disagreeing with are a bunch of stupid cunts, essentially, just creates bad feeling. And a shortage of sympathy in a really rather ordinary situation where there is room for interpretation, given the lack of real facts at our disposal to make a judgement on.
You also have to take responsibility for the way your behaviour, here and in RL makes people react to you.
Well, you don't, but it might help not to put people's backs up.
