Acorn

As flake is to blizzard, As curve is to sphere, As knot is to net, As one is to many, As coin is to money, As bird is to flock, As rock is to mountain, As drop is to fountain, As spring is to river, As glint is to glitter, As near is to far, As wind is to weather, As feather is to flight, As light is to star, As kindness is to good, So acorn Is to wood
