The reticent volcano keeps
 His never-slumbering plan;
 Confided are his projects pink
 To no precarious man.

 If nature will not tell the tale
 Jehovah told to her
 Can human nature not survive
 Without a listener?

 Admonished by her buckled lips
 Let every babbler be
 The only secret people keep
 Is immortality.

I really liked the volcano imagery, especially because it suggests that a silent person has a never slumbering plan, and he never confides it to those it affects - the men who eke out a precarious existence on its slopes. I also really liked the last two lines - I think the way immortality is used to illustrate that people can never keep things to themselves is amazing.

Basically I like this poem because most people talk too much and just can’t keep quiet, even when I ignore them and maintain a stony silence. One more thought - why are people so uncomfortable even with friendly silences? Why must they rush to fill them in with higgledy-piggledy words?
