Oh, yes. Sometimes I don’t understand them. I had a dentist who had been seeing me for several years, but now he has moved to Australia. And I don't want to end up with just anyone, so I got in touch with him. He recommended another doctor, and a month ago I thought I had made an appointment with him. But after driving 20 miles, I found out that they had changed their mind and scheduled me with a random one. I couldn't wait any longer and had to get treated by him that time, and it was very unpleasant for me.
