I was wondering about past simple and present perfect lately. It was a long path of understanding these 2 tenses, I think I finally understand the meaning of "context" that can occur or not.
When there is a context (last year, since, for) then the sentence has a certain tense. But without it I can only judge it in my own perspective, for example:
I borrowed it from my friend (emphasizing the past action of borrowing in the past, even if he/she shows in the present this particular item he/she is going to use or something, still he/she is relating to past action)
I've borrowed it from my friend (emphasizing the present situation as well as mentioning the past action he/she did but is still relating the present situation that he/she is having this item and he/she can use it.)
I don't know if my thoughts are reliable, but I'm summaring the whole knowlage I've gained till now (I don't know if "till now" is grammatically correct, if not then I'm sorry) I want to use this summary (of course if it's correct) as a message for those who doesn't understand the difference without the context like (for, since, last year, etc.)
What do you think about it? Oh and I want to ask you a favor as well. What do you guys think about the grammatical side of my "small thought"?
PS. There are also some verbs that doesn't suit my thoughts for example "I promised" it's more a past action that the promise was stated, but if I have to think about it in the present perfect version, then I could say that "I've promised" can state that what he is doing right now is because of this promise. But I think that some verbs doesn't suit it.
PS 2. Im refering here only about no context situations, there are some rules about that but aren't clear when it says about "result", it more likely means that can be used interchanable depending on what do we want to emphasis. What do you think about what I wrote here ?
