I have four kids, two grownup and two at home. Three girls and a boy. The two youngest are girls aged 14 and 13 and they are driving me nuts.
They are at the stage where:
they do not recognise body language - like when I frown or sigh they don't get that these are the warning signs that Mum is not happy
they take sarcasm literally - like when they start arguing about who's turn it is to do something and I say: "Oh, it's OK. I'll clear the table, I'll load the dishwasher, I'll get in the washing, I'll hoover. You go and sit and watch TV..." and they do just that
if I yell at them they accuse me of child abuse
if I ask for help around the house they inform me that slavery was abolished hundreds of years ago
nothing is fair
they think money grows on trees
they don't get that the more they pester their stubborn Dad about having Facebook, the longer he will take to say yes (even though I have told them that)
they don't get that to be treated like a teenager, they have to stop behaving like a five year old
Today my email subscription to Zen habits turned up this classic post: The Zen Habits of Teenagers - I have printed it off and stuck on the fridge using a fridge magnet.
