Dear Miss Snark,
I am going to a conference this weekend and have just learned that an agent I queried a couple of months ago will be there. As recommended by her agency's website, I sent the first fifty pages with the query.
Now, I have no intention of seeking out this agent at the conference and pestering her. (I am pretty good at seeking, but pestering is definitely not my forte.) If I am talking to her at dinner or something, however, should I allude to that fact? I don't want to be a nuisance, but it also seems somehow disingenuous not to mention it.
Stay quiet as the proverbial church mouse.
There is no up side to telling her she's got your pages.
Chances are she hasn't read them; if she has, she won't remember them unless she's asking for more.
