Try this to relax a bit for a minute when you're still working at 6 p.m.

Read recipes on Epicurious. When you find a comment about an intention to experiment with something recipe related, suggest to the commenter loudly, out loud, that is, and not keeping your voice down, that he experiment with something else, something much more vulgar, "Why don't you experiment with ______ instead?!" Utter something so vulgar that once you've suggested it you have to look around quickly to make sure nobody heard you, despite your being the only English speaking person in your office. That's what I call relaxation!
