I overheard a Product Owner tell her colleague how much she hates another manager. She said “She has been messing with my frontend!” which I wasn’t sure if that was meant to be a funny pun or not, but it sure was funny.
I was convinced I’d misheard her, but as she explained further, it sounded like it was actually an accidental pun. She explained that her ordered backlog of work had been intentionally sabotaged. She made reference to a “Frontend backlog” so I assumed she had 2 streams of work: a “Front-end” and “Back-end”, and it was the Frontend one that had been sabotaged.
I’d advise that you don’t touch people’s frontends without permission, and definitely don’t do it in work-time.
