In Vera Hessey's "The Frog and the Bird," a frog and a bird look at the world from their own point of view. The bird, who would not like to fall in the water because it can't swim, worries that a frog she sees will fall off the mossy log where he is perched and into the stream, which is full to the "brim." The frog, however, reminds the bird that it need not worry, for he knows how to swim.
The frog then looks up and sees the bird perched high up on a tree bough. He worries the bird will fall and get killed. The bird, however, informs the frog that it knows how to fly, so it isn't concerned about falling.
The poem is a lesson about how we project our own fears and limitations onto others. We tend to see others as exactly like ourselves and, therefore, wanting what we want and fearing what we fear. However, different people, like the personified animals in the poem, have different strengths and weaknesses and tend to know their own limitations. The poem therefore sends a message that it is good to trust others to know what they are doing—though it also doesn't hurt to ask and make sure they are all right—and to remember that other people might have a different life context than we do.
