hi guys, it's me again
I wonder what's the difference between 갔어요 and 갔었어요? which one exactly is the past tense? I suppose the first one is, right? Then what's the second one?
And I've seen 아직 멀었어요 quite several times. I know what it means, but I dont get why it's in past tense.
And another question! I'm a bit confused with that 는 and 은 as in past tense. Just now I saw this expression 화났는 줄 몰랐어in one of the lessons here. I wonder why not 화난 줄 몰랐어. With past tense, sometimes it's 했는,sometimes it's 한. Can you guys sort it out for me?
Thank you^^
