Do you have a Do Not Disturb sign on your office door? Mine says:
*In the interest of full disclosure, “work” is a relative term. Also, the conditions under which it is okay to disturb my “work” are presented in inverse order. Coffee first , and then zombies, and then only if you can’t put out the house fire on your own. Clear? Now go away and let me “work”! Where did I put that pillow?
