I went in to work this morning and did a few things that I could only do at the office, then photocopied some files and came home. I've been reasonably productive, and much happier, since.
Hint: The leaf of one's dining room table makes an executive-sized lapdesk that fits two files and a laptop.
Unfortunately, that I am answering interrogatories means that Bill Barr's suggestion of a whiskey and lemonade cure for what ails me will have to wait. But hey, there's always this evening...
