good luck, shaney, your leg sounds awful. There must be something somewhere that will treat it, even if it's only a rare Chinese herb only ever seen by Tibetan yak herders.
neti, I get the cicadas too. I have them all the time so I don't really hear them unless I listen for them. But I don't hear anything else much either. It's not so awful, jude, though being part deaf is never much of a help socially.
I went to the exhibition this morning, but didn't bother cutting my toenails again for it. Then we went to look at the mirrors in Covent Garden

and then the Palmyra arch in Trafalgar Square

(I'm not in the photo, when we realised Boris was going to be there we ran and hid in the National Gallery and only came out after he'd gone).
