Yes you made a mistake, but when you meet with open defiance from a 5 year old, your patience can snap. But perhaps she IS a horrible child, but that is a criticism of your DD, so she is resentful and defensive. But HER behaviour standing you up, is bad behaviour too. Possibly she knows that her parenting needs work, and is as angry that it hit home.
But with small children you have to tell them that their behaviour is horrible and you expect better of her, not that SHE is - even at 5. But did your DD not play up when she was overtired, or perhaps just missing mummy? - did DD tell her that it was only for the evening and that she would be there the following morning?
