Hmm. It now occurs to me that it's been more than a month since you said that, and she never did. Do you happen to know if the address on her LJ is a sensible way to get in touch with her, or indeed if she's still even in the right town to have her brolly returned?

No I don't; you could try giving her a poke on LJ and an email, then if she doesn't reply you end up with a free brolly :)
