["I have a dentist appointment next week. I hate going to the dentist. I don't want to go."]
I went through that for like 5 years.  Ended up finally going and they've made a lot of advances in comfort since I last went before that.
I hate going to the dentist. I have an appointment coming up and I don't want to go. I have a tooth that has been hurting me for awhile and I have already put it off.
