걱정도 팔자
worry-TOO sell-PROP
Let’s even sell worries.
“Don’t worry about it” or “You worry too much” or even “None of your business.” It doesn’t feel particularly polite.
I also found a version with the ending -군 (i.e. 걱정도 팔자군) in the daum.net dictionary, but that is much more puzzling to me grammatically, since I had no idea an exclamatory and a propositive could combine that way: a sort of exclamatory proposition?
