Bonus Skill Idea: Proverbs/Sayings
I think a great bonus skill would be proverbs and sayings! Maybe even multiple bonus skills, as there are so many great proverbs and sayings.
I had to look up "haba" in the Kamusi and then saw this saying, listed below at the "habari entry":
Habari mbaya zina mbawa, lakini habari njema hutembea kwa mikongojo
(nb: Mkongojo is a staff, walking stick; mbawa=wings)
...bad news has wings, but good news walks with crutches/walking sticks
It is like the English expression "bad news travels fast"--and reminds me also how we are quick to complain with all the small errors in the Swahili course, but really it is so helpful and a lot of it works well, and we've learned a lot through it, we just don't say so as quickly ;-)
