In a West Indian setting, a brown-skinned brother and sister speak in unison and singly--about a day of being a brother and sister, just like the title says (except that one wonders, reading the title, what makes this day different from every other day). Sometimes they quarrel, sometimes they look out for each other, sometimes they celebrate their togetherness--all in poetically-set word patterns: ""Together:/ Brother on the beach/ Sister/ on the sand./ Rolling/ in the water./ Strolling/ hand/ in hand./ Sister sand/ and brother/ beach:/ together/ each, together/ each. / Reach./ Reach./ R e a c h."" Presented simply and straightforwardly, this would be pretty ordinary, slightly strained stuff (and pretty jog-trotty rhythm): ""Today we are sister and brother. Today we are faster than run. Today we are brother and sister. Today we are closer than one."" In full color, some of the beach scenes have a travel-poster appeal; but sibling frictions and bonds are depicted with far more spirit and immediacy elsewhere.
