I'm sorry to say that I cannot go to the bookstore with you on Friday afternoon. I have just found that I have to attend an important class meeting that afternoon. I hope the change will not cause you too much trouble.
Shall we go on Saturday morning? z.xxkWe can set out early so that we'll have more time to read and select books. If it's convenient for you, let's meet at 8:30 outside the school gate. z.xxk If not, let me know what time suits you best. I should be available any time after school next week.
I don't think I can make tomorrow's appointment as I am having a really bad cold at the moment.
I am so sorry about that.I went to see the doctor yesterday and got some medicine.I thought I might get better today,but I still cannot get out of the bed now.I am having a terrible headache,and coughing badly.
Can we rearrange the appointment?I will be free from next Tuesday to Friday,and I think I should be completely recovered by that time.I promise you I will see you next time.
