Professionally ignore people with style.

Thank you for your email. I will be ignoring it on a delay. I am away from the office for a general and none-of-your-business absence. The codebase has endured worse than my temporary disappearance. I will respond when I return, which is earlier than some expectations deserve. If this is urgent, notify the engineering lead or the incident channel. Thank you for your measured response to my unavailability.
