It is not often that someone comes along who is a true friend and a good writer.Charlotte was both.

-White, E(lwyn) B(rooks)
  Charlotte'sWeb, ch.22.

Even so for me a vision sanctified The sway of death; long ere my eyes had seen Thy countenanceöthe still rapture of thy mienö When thou, dear Sister! wert become death's bride: No trace of pain or languor could abide That changeöage on thy brow was smoothedöthy cold Wan cheek at once was privileged to unfold A loveliness to living youth denied. Oh! if within me hope should e'er decline, The lamp of faith, lost Friend! too faintly burn; The may that heaven-revealing smile of thine, The bright assurance, visibly return: And let my spirit in that power divine Rejoice, as, through that power, it ceased to mourn.

-Wordsworth,William
