Could you, please, explain me using "Perfect" tense in the following examples:
1. When a car had slowed down and picked me up, I had been real happy
2. that extraordinary interview with George last night necessiated rememberance. It had been so unexpected, so frightening. Wait - had it been so unexpected?
(IMHO, All red had been in those examples I can change to simple "was", i.e. use "Past" tense. I just cant understand why the author used Perfect tense there...)
