Hi Mum,

I've gone been to the gym and I've also gone went for a run with Karen. I've ever never been so tired! The dog has have had her dinner, but I hasn't haven't watered the plants. William have has taken a snack and he is has gone to play football. He'll be home for dinner, but I won't. Karen's mum has invited me to eat with them. I've ever never have dinner with them before! Dad says he's have has to work late and he'll call again at six. Have you ever seen my new jeans? I can't find them. I also lost my new T-shirt.

See you later,

Milly
