Dear Tom,
How are you? I hope you are well. I'm writing because I've got some bad news. I'm afraid I can't come for the weekend. My sister is sick and I must help her. She has got temperature, cough and sore throat. She can't be alone right now. I must stay with her. I'm really sorry.I'll be in touch soon.
Best wishes,
Margarett
