We are experiencing optical difficulties. WTF will return as soon as we have them resolved.
Specifically, I'm having some eye trouble and am working on getting it diagnosed. The symptoms aren't particularly drastic, just a bit iritating and mysterious at the moment. I have some 'blind spots' in both eyes that make reading, writing, and anything involving focused use of eyes a bit more trouble than they're worth.
More news as it develops.
On a related note:
After being told a few times over the past two days by optomologists that "smoking is bad for your eyes", I found it particularly ironic to find a large framed Hockney print in the retinal specialist's office.
