chawawana idya nehama mutorwa anehanganwa

If you get a fortune, share it with your relatives; strangers easily forget the favor.

What it means
A stranger's gratitude fades once the favor is forgotten, but family remembers, and sharing deepens the bond. It's practical advice as much as feeling: who you're generous with matters.
