Dear Person I've never seen before in the office, crop-dusting the office with a not-so-surreptitious can of Lysol and a self-satisfied smirk:
Your chemical attack on personnel in this wing of the building has been accepted for the Act of War that it clearly is. A counterattack may or may not occur when you least expect it. Comport yourself accordingly.
XOXO,
Me and all the other personnel in this area now gasping for breathable air.
