Actually, I think there may be a grain of truth in this story.
I think, possibly, the writer has a cousin "Jennifer", who she doesn't like very much. Possibly "Jennifer" also became romantically involved with a man the writer would rather have become involved with her.
Everything else? Wishful thinking.
I absolutely agree. This was my exact take on this story . . .
Some poor girl, sweet and kind, intelligent and misunderstood, stands in the wings and watches as the man of her dreams marries her cousin . . . the cousin with the Breck Girl hair and the straight white teeth. Watches as the boy who smiled at her that way
in Biology in the 9th grade, only 7 short years ago, watches as he marries the cousin who's so shallow and self-involved, the one the family thinks is so pretty and funny and nice . . . but the girl in the wings knows how she is! The cousin is a great big meanie! She makes fun of the girl in the shadows, with her braces and glasses and stringy hair and dumpy sweaters!
That boy will see the girl at the rehearsal dinner, see her with her unassuming brown dress, and he will look through all of his fiancee's fake blond hair and fake tan and fancy clothes, and he will remember that moment in English, in the 7th grade, when he handed the girl her test with a special wrist flick . . . and they will be reunited.
It will be beautiful.
Just like it was in her faaaaaaaaaaaavorite movie.
No, not _Lord of the Rings_. She doesn't even have that costume anymore.
