in which excerpt from John Donne's a valediction forbidding mourning indicates what the speaker does not want his wife to mourn?
a. while some of their sad friends do say /the breath goes now
b. out two souls therefore, which are one/though I must go, endure not yet
c. moving of th' earth brings harm and fears/men reckon what it did
d. thy firmness makes my circle just/and makes me end
