This poem offers an extended metaphor. which two things does longfellow compare? he compares the wind to a vine and falling leaves. he compares a sunny day to the better days he had in the past. he compares people who do not experience pain to the hopes of youth. he compares a difficult time of life to a dark and dreary day.

tell me the anwser when u get it

This is the poem: The day is cold, and dark, and dreary;

It rains, and the wind is never weary;

The vine still clings to the mouldering wall,

But at every gust the dead leaves fall,

And the day is dark and dreary.

My life is cold, and dark, and dreary;

It rains, and the wind is never weary;

My thoughts still cling to the mouldering Past,

But the hopes of youth fall thick in the blast,

And the days are dark and dreary.

Be still, sad heart! and cease repining;

Behind the clouds is the sun still shining;

Thy fate is the common fate of all,

Into each life some rain must fall,

Some days must be dark and dreary.

as university of miami psychologists debra lieberman and adam smith pointed out in a recent article in the journal current directions in psychological science, humans have social and psychological mechanisms to deter incest. with very few exceptions, marriages between brothers and sisters and between parents and their children are verboten in every human culture. the primary psychological anti-incest mechanism is the yuck response. even the idea of sex with their mom or dad, bro or sis is upsetting to most people. the psychologist jonathan haidt has found that nearly everyone is repelled by the prospect of brother-sister sex, even in hypothetical situations in which there is no chance of pregnancy).

the biological cost of incest

this raises an interesting question: just what’s so bad about incest? sure, having sex with your dad or your sister seems gross — but why? some anthropologists have argued that incest taboos are learned social conventions. this explanation, however, doesn’t make sense to me as it does not explain the widespread existence of anti-incest mechanisms in creatures ranging from cockroaches to chimpanzees. second, the incest taboo is about as close to a universal law as human moral rules get.

why should mechanisms to avoid incest be so widespread both in nature and across human societies? the answer is simple. the problem with having sex close with relatives is that there is an astonishingly high chance that your offspring will be born with a serious birth defect.
