너나들이, neonadeuri, is a friendship where the two of you say 너 and 나 to each other — you and I. No titles, no polite endings, nothing held out at arm's length.
In front of someone like that there is nothing to dress up. You do not add anything to what you have done well, and you do not cover what you have not. Whatever you put out will not be held against you. People set their breath down in company like that.
They say that as you get older the number of people you know goes up and the number you are on those terms with goes down. More relationships, higher thresholds.
