This question already has an answer here:
I'm not a native English speaker and I find English quite difficult and confusing and one of the reasons is because of its tenses—which I find challenging and rewarding once everything becomes clear—so I would like to ask which of these two are correct:
- I thought we talked about this before
- I thought we had talked about this before
I've read somewhere that I should use the past perfect tense to indicate past action that occurred prior to another past action, and Past perfect verbs are always formed by using adding ‘had’ before the past participle form of the verb.
E.g. had + talked
In the examples above, "thought" and "talked" are both past actions, but "talked" happened before "thought", so my guess is that sentence no. 2 is the correct one, but I'm not so sure because sentence no. 1 is used most of the time in movies and conversation.
What are your thoughts about this?
