Professionally ignore people with style.

You have contacted a person who is currently somewhere else on purpose. I am away from the office for a general and none-of-your-business absence. If this is a hotfix, please make sure it is not actually room-temperature confusion. I will reply when I return from wherever I flung myself for survival. Serious outages should go through the normal engineering escalation path. We all make choices. This message is one of mine.
