I was asked to fill the blank below preseving the meaning of the sentence.
It was not necessary for him to take any warm clothes, so he travelled light. He ________________________ take any warm clothes with him, so he travelled light.
I wrote "He hadn't needed to" what was wrong as "He didn't need to" turned out to be correct.
I used the past perfect, as I imagined it like so: PAST: he travelled; EARLIER PAST: he hadn't needed
In similar topic I've found this:
You can 'know' something at any time. You can realise something long after becoming aware of it, as 'knowing' requires a conscious thought to realise it. You can only 'notice' something when you're present, there and then, to be able to notice it.
I guess there is a similar case with "need" and "travel"? If so, is there wider explanation how to move comfortably between those verbs like "know, need" and "notice, travel" in past tenses? This is very confusing when your native language has one past tense.
