Twin-Growth

I would not wish thee other than thou art; I love thee, love, so well in every part, That had I power to change thee In form or face or mind, I could not find The heart to re-arrange thee. For we were made to suit each other, sweet, Apart, uneven, but when join'd, complete, With powers and failings matching In each as strictly well As in some shell The sharp teeth interlatching. And so I would not have thee change, for fear The valves might open and gape a little, dear. But we are like the weather A-changing every day, And so I pray That we may change together -- Change like twin shells, that nothing can estrange, But ever changing never feel a change: So grow for one another That each may aye present The complement That doth fulfil the other.
