Yesterday I had a terrible toothache, and today I decided to see a dentist. I usually go to the doctor when I am sick. At this time yesterday I was walking to and fro as a mad man because of the pain when I picked up the phone and decided to make an appointment. I have never done that. But I am driving my beautiful car right now while I am thinking that soon I will have my tooth fixed. It's half past three. The appointment is at 4 o'clock and I am hoping I'll be there on time.
