6) I will just tell him that he owes me $1 and pay me back
whenever it is available, but without expectations that it will be
returned.
Coz if B goes for Choice #1, it may leave an impression on A that
he's a cai tou and it may become a point of reference the next time
B lends money to A. Like, "wah lau, that time you gave me $1 also
nebber mind. now treat me one ice-cream ngiow so much." This one
more shang gan qing, I think.
Then for my choice, if A does pay back that $1 someday, it shows
that he is honest / not forgetful and B will find him more reliable
and trustworthy in the future. So with $1, B can tell whether A is
reliable (and gets back that $1), or not (and loses that $1). I
know $1 may not mean much, but at least B will have a better idea
on what to do if A wants to borrow $100 from B in the
future.
