Dear Kate,
   I'm sorry to tell you that I couldn't go to see the film with you this Sunday. My grandmother suddenly fell ill and was taken to hospital this morning. I have to take care of her this weekend. The doctor told us it will take about one week for her to get better. So I think we can go to the cinema together next weekend.
   Please allow- me to say sorry again!
