I see the crepey teens, and Mrs S's DH, are living down to expectations. What joy. I've had a certain amount of backchat from DS of late, and he's becoming bad mannered. I'm going to have to take him in hand. For example, our good friend invited us, impromptu like, back to her house after school yesterday. She had her car, but inevitably the boys started squabbling about who was going to sit on which booster seat. Normally DS would just do what he's told, but he refused to move. So I suggested a game of rock, paper, scissors to resolve the issue. He folded his arms, and said with his nose in the air: "That's not the way it works, mummy." Can't imagine where he gets that from. 
On the other hand, he was Star of the Week for the improvement in the presentation of his work, after the grief I gave the teacher over the 'appalling handwriting' comments. He stood there at the front of assembly, with a shy but proud smile, hair all over the shop, coat drooping, shirt hanging out. So sweet.
