The past perfect serves a purpose: When describing things that happened in the past, it allows us to discuss things that happened before (i.e., in the past’s past). However, a procession of had, had, had makes writing sound clumsy and labored, especially in a narrative. I treat past perfect similar to constructions using that: Unless it changes the meaning of a sentence, toss it out.
A: She had called me weeks earlier, and now I remembered what she had told me.
B: She called me weeks earlier, and now I remembered what she told me.
A is strictly correct grammar, but weeks earlier already implies that the phone call happened before my remembering it, so I would favor simple past tense (B). Am I correct, or did I go overboard in my attempt to avoid the past perfect?
