Our soon to be 15 year old daughter who is well behaved at school etc and does do jobs when we ask etc. However, she never wants to spend time with us and is constantly walking out of rooms when we walk in. We have come to dread the holidays as I work from home and she just spends all her time in the house. She doesn't seem to meet up with her friends or anything and often goes days without going outside. This is despite having a good lot of mates at school, she just doesn't bother with them when she is not in school. She has a huge temper and has just cancelled her birthday party on friday mostly to spite us I think. Is this normal, what can we do??
