I share that part of my space with the fax machine, the copier, the water cooler, a storage cabinet and the microwave [...] I'm often edgy and exhausted at the end of the day
I find it helps to banter with visitors. When David comes by to copy some papers, call over "Dave! Makin' copies!" Switch things around to avoid boredom like "Davey wavey! Makin' copies! Copies for The Dave Man! Copytopia in Daveland! The Davemeister whips out the copies! Copyrama and a Dave-alama ding dong! Dave!"
