It occurs to me that were someone to start working out who's who in this blog then Elphaba could cause some confusion that would potentially be quite awkward.
So, just to clarify things, Elphaba has (to the very best of my knowledge) not the slightest interest in dust.
The lady who might-be-but-isn't Elphaba and who is interested in dust is unlikely to feature in these postings, and if she does might simply be called not-Elphaba.
I really must leave soon.
I'm tempted to write more about Elphaba, or about Isn'tShe.
But I shouldn't, and (this time at least) shalln't.
