Four short lines, and a mood swing in the gap between the second and third. Elisabeta's "By the beach" opens in pure delight and ends in a quiet panic, and what makes it work is how little the speaker says about either feeling.
The first stanza is all brightness. "The sun is shining bright / Oh, it is so shiny": the same idea is said twice, as if one description weren't enough. "Shining" and "shiny" share a root, and the repetition has the breathless quality of someone looking at something dazzling and running out of words. The little "Oh" is the most spoken-sounding moment in the poem, a gasp. "Shiny" is also a slightly odd choice. It is the word we use for new coins, polished shoes, toys, surfaces. It makes the sun sound like an object, glossy and almost too perfect. Sunlight on water is exactly that: a glare that looks beautiful and tells you nothing about what lies beneath.
The second stanza turns on a change of grammar. The sun was given two adjectives, "bright" and "shiny", but the sea gets none. It gets only a quantity: it "flows a lot." The poem measures the sun by quality and the sea by amount, and that shift quietly changes the atmosphere. Beauty can be admired, but a lot of anything is something to be afraid of. The verb is unusual too. Seas wash, roll, crash or swell, while rivers flow. "Flows" suggests water that moves steadily and without stopping, as though the sea had no edge. Whether this is a deliberate choice or a plain-spoken one, it makes the sea feel boundless.
Then, for the first time, a person appears: "I think it's gonna drown me." Until this line the speaker has been invisible, a pair of eyes taking in the scene. The "me" at the very end is also the last syllable of the poem, and it is unstressed, so the line seems to trail off into the speaker's helplessness. The line is also the longest, seven syllables against six, six, and five, so the poem stretches as the fear arrives. The first two lines are close in length and steady in rhythm (the opening one is almost a regular three-beat line: "The SUN is SHIN-ing BRIGHT"). The third is clipped and short, and the fourth spills over.
There is no end rhyme, and that suits the poem. "Bright" and "shiny" echo each other in meaning rather than sound, while "lot" and "me" do not chime at all. A neat rhyme would have made the fear feel tidy and decorative, and instead the poem ends unresolved.
The tone of that last line deserves attention. "I think" and "gonna" are casual, the language of someone chatting or texting. The fear is delivered with a shrug, which makes it more believable. People rarely announce terror in grand language; they say something small and slightly embarrassed. The hedge "I think" leaves open whether the danger is real or imagined. And the title, "By the beach", may be telling. The speaker is not in the sea but beside it, at the border between land and water. The drowning, then, is probably a fear rather than an event, which is to say that the sea only has to look big enough.
The poem can be read as literal, a swimmer or onlooker unnerved by the waves, or as something broader. The poem never says what the "sea" might stand for, but the pattern it sets up, of delight giving way to feeling overwhelmed, would fit many situations in which something lovely turns out to be too much.
What makes the poem worth reading is that it does so much with so little. In four plain lines, it catches a feeling most people recognise: the moment when a perfect day, or a beautiful view, tips over into awe and then into fear. It doesn't explain itself or moralise, and it trusts a simple, honest voice to carry the contrast. The sun is shining, and the speaker is still afraid.
