Dad, it's Quinoa not Couscous

Koh: Dad served us leftovers tonight while Mom was out, and sometimes I think he doesn't even know what he's putting on the table.   For example tonight he put out re-warmed quinoa (keen'wah) and asked me if I liked this couscous.   I told him quickly "Dad, it's quinoa, not couscous."   I mean come ooooooooon Dad, EVERYONE knows the difference between quinoa and couscous.   (Dad's editorial: I was at least 40 before I learned of either of these grains, and now I have a 4-yr old smart-ass correcting me?)
