history: I have to go get some shots at the doctor this week and i am not looking forward to it.  I don't like shots at all I have to go to the doctors next week_comma_ and I am not looking forward to it at all
current: I wouldn't look forward to that either. What are you going in for?
next: I have to get some allergy shots.  I hate getting shots.  They are no fun at all.  I get so nervous just thinking about it
