First, her post was not in response to a question, so your analogy doesn't apply. It is more akin to starting a story with "Well, it finally happened." If you stop there, of course you don't know what happened or why the word "finally" was used.

"How long have you had that cough?"

"Since the party at Bob's place about a week ago. He's a friend of mine with an outdoor pool, and it was a bit chilly."

I see nothing ridiculous there.
