Four short lines, and a whole relationship seems to hang inside them. A speaker asks someone loved to keep away, and the reason given is not a danger they can name but one they cannot measure: "for what you will endure / I am not sure." The poem's force comes from that admission. It is a warning that confesses it doesn't know what it is warning about.
The poem has no title, only three asterisks, and it begins with a lowercase "and." We seem to walk in halfway through a conversation, or halfway through an argument the speaker has been having with themselves. Whatever came before is missing, so the plea arrives like something said at a doorway, hurried and unplanned.
The tone is carefully split. "Please" and "my dear" are soft, while "don't come near" is blunt: three one-syllable words, each of which can take a stress. Tenderness wraps around a hard request, and the affection is not cancelled by the refusal. It is the reason for it. The rhyme adds a quiet irony, because "dear" and "near" chime together even as the sentence tries to pull them apart. The sound binds what the grammar wants to separate.
The second couplet is where the poem turns. The verb "endure" is a chosen word. The speaker could have written "suffer" or "face," but "endure" suggests something that lasts, a thing borne over time rather than felt in a single blow. And look at "will." The speaker is confident that something is coming. The doubt attaches only to its size or nature. That makes the uncertainty less comforting than it first sounds. "I am not sure" does not mean "perhaps nothing will happen."
The construction is as compact as the sentiment. The poem rhymes in couplets, and the lines run roughly four, three, six and four syllables. The third line is the longest, and it carries the burden, the thing the beloved would have to bear. The last line shrinks back to four syllables, as if the speaker, having pointed at the danger, can only fall quiet. The rhyme of "endure" and "sure" matters most. Rhyme normally gives a sense of closure, of things clicking into place, and the final word is "sure." But it arrives behind "not," so the sound promises certainty while the sense withdraws it. The jingling, almost nursery-rhyme pattern sits oddly against the sober content. That could read as childlike honesty, or as someone keeping their voice steady by keeping it in rhyme. The poem doesn't say which.
There is no punctuation apart from the apostrophe in "don't." The words run on in one breath, and judging by that, the speaker might fear that stopping to place a comma would give them time to change their mind. The pronouns work in a similar way. The first three lines are about the other person, with "my dear" and "you." The speaker's own "I" is held back until the last line, and when it arrives it is only to admit ignorance. The speaker never explains themselves, and never says what they are.
That refusal to specify is central to the poem. The danger could be illness, grief, anger or a troubled state of mind. The text gives no evidence to choose among them, and that openness lets readers bring their own situation to it. There is almost no imagery in the usual sense, no metaphor or picture, and the only physical idea is distance. The whole poem is built on the gap between two people, and the question of whether to close it.
That is what makes it worth reading. It raises a real moral puzzle in a handful of words: is keeping away from someone a form of protection or a form of abandonment? A confident command would have sounded cold, while this plea, with its honest doubt, sounds human. And because the speaker is "not sure," the door is left slightly open. The poem ends without telling us whether the dear one will listen.
