Well, I now know why JMK disappeared yesterday.  Apparently he got offended by an e-mail I wrote, even though there was nothing in it meant offensively.  Oh, well.  e-mail "tone" is so difficult sometimes.  I'd asked him for help in terms of doing a Portland signing, which he said he'd be glad to do.  Hadn't heard anything in a month so I sent an e-mail asking if there was any news.  His reply was that the two stores he'd contacted either weren't interested or hadn't gotten back to him.  It was a tersely worded e-mail that I found a bit unfriendly, but again, e-mail tone is sometimes easy to misread.  I replied that it would have been nice to know this information a few weeks ago - meaning I might have been able to do come up with a different plan.  That e-mail response seems to have upset him, although I certainly meant nothing by it.  He wrote back that he'd only heard the final "no" the day before.  And that was it until I got a rather scathing e-mail from his wife.  I've responded to that in what is hopefully an even-keeled manner, and I'm hopeful it will all blow over and that he'll be back.  Color me baffled sometimes, really.
