Background: Process issue in the plant that the workers said was a software problem. I’m a Software Dev Manager

Exec: This is broken and it is a software problem. We just noticed it this week.

Me: Couldn’t have been us, relevant code was changed this time last year. Sounds like a process issue.

Exec: Can you give me an exact date it was changed last year?

Me: (Seriously, WTF?... checks git...) It was changed on December 2nd, 2016. Couldn’t have been us.

Exec: Can you detail that change for us?

Me: (GTFO) No, not my problem, stop trying to make it my problem.
