Dear Sarah,
I’m writing because I want to apologize to what I did last week. I’m really sorry. I know we said 8:30, and I would’ve gotten here on time if everything hadn’t gone wrongly. I was late because my watch broke and I didn’t know what the time it was. So you see, I would’ve arrived on time if my watch hadn’t broken. Then I have to walk because I’d missed the bus. And then I fell over and my trousers got dirty, so I had to go home and get changing. Then I decided to catch another buses, but it was too late. I would have phoned you and my brother had taken my mobile phone. Anyway, I hope you aren’t too angrier with me. Hope to hear you soon
