Dear T

So I did get out of bed. I went grocery shopping and during that one short time I couldn't take a call, you called. Why did you call? Do you need to cancel tomorrow? Are you sick? But if you'd be sick then you couldn't have called from the office. Unless it was one of your collegues. I'm not going to call you back. If it was you, then you could be in session and someone else would answer. So it has no use for me to call you. If it's important, then you will call back. If it was you.
But now I'm worried. It has to be about tomorrow's appointment. Otherwise you would probably have emailed me.
Why did you had to call when I couldn't answer it. Now I'm wondering the whole time what it's about. I'm worried. Please call back.
