So now it's the day after the signing. 1,200 people were in the signing line (an attempt to cap the line was abandoned after a riot was threatened, I learned afterward) and records were broken for books sold at a signing (700 plus) and I was out of there by 11:30 at night, and that was all good.
The people were friendly. There were amazing gifts in quantity. My two phrases of Portuguese impressed everyone, and I managed to do 200 people an hour mostly because no-one really tried to stop and chat. But by the end of the signing I had utterly and completely lost my voice.
Now, a day later, I'm communicating in something between a whisper and a croak, and doing a lot of Harpo Marx style wordless stuff, and I'm hoping I can talk by the time the Argentinian signings and interviews start.
I suppose it's better that something like this happens now, rather than on the AMERICAN GODS tour.
