Ok, this is not weighty enough for GQ, and it’s kind of a dumb question, too.
I wrote this poem, a sonnet to be precise. The last two lines popped into my mind pretty much fully formed. As I was typing them, they seemed very familiar. Seems to me there are two alternatives:
[ul]
[li]Deja vu[/li][li]I read them a long time ago and some long lost memory cells came back to life just then[/li][/ul]
I went to Google and did a search on the key words in the last line (four of them) and got about a zillion hits. I only waded through the first couple of pages, because nothing was close. Then I did a search on the exact phrase of the last line (which seems especially familiar) with and without punctuation . It returned no matches. I don’t want to claim it as original if I dredged it up out of my memory banks. Does anyone have any better ideas than what I did for a search on a line in a poem?
