I've done the wrong-burner thing more often than I care to relate. I'd probably still do it frequently, but I heat water for tea in the microwave now (it seems to be the most efficient way, surprisingly.)
I've had that feeling all day like someone has just kicked me in the solar plexus, but it seems to be getting better. I got a nice book to read (paper-- this one's not available as an ebook, even in the UK) and a few little creative projects to fiddle with.
Which reminds me! I need to finish uploading and configuring the Squirrel section of the store.
