Believe it or not, you may be feeling just a tad on the excessive side at the moment. Not that you won't get up at the usual time, execute the usual routine and perform as well as always on the job. But you should be aware that anyone who's speaking with an especially charming accent, wearing something especially unusual or telling a story you've never heard will be more than enough encouragement to keep you up late. Better get an extra supply of espresso for the AM.
