What does it mean when the poet compares Twilight to “a velvet curtain”

The backyard then

Hello. The part of the poem where this comparison takes place is:

"Then there was the shady dirt

under the old maple tree where I read, cradled or

sinking between dying tentacle roots.

Was there ever any glory there? I can remember

a few humid evenings through the crack of the back door.

Twilight hanging like a velvet curtain, the thinning

pine trees at least only silhouettes."

The author compares twilight with a velvet curtain to symbolize the moment when he can no longer have a point of view, because that moment has ended.

Explanation:

Twilight is the moment when the sun has just set and there is no longer any incidence of its light in the region, beginning the night period, that is, twilight can be used to symbolize an end.

A velvet curtain, in turn, was used to symbolize the end of a show, as it was lowered to prevent the audience from having a view of the stage, since the show was over.

In the poem, the author compares the velvet curtain like twilight to show that the darkness of the night ends the author's point of view, preventing him from maintaining it.

dont tell me what to do

explanation:

it's important for any number of settings.   but then i'm a retired teacher and my view may be biased.

it certainly will not weigh as a minus when applying to a college, while poor grades always work against you.

other factors are important like what you do to improve the community.
