I think this song describes a sibling that lives in the shadow of his/her other sibling. Some lines that support this: "Let me introduce you...tickle out", "She will rise just to embarrass me", & "Desire it grows and grows, like a strawberry, not a rose." That last one really shouts the meaning out at me, saying that the shadowed sibling is not the rose the other is.
