🎬Monday morning, Victoria is in the office while David is working from home.
Victoria
Why are you OOO? The heating in your home office isn't that critical.
David
It's actually a total meltdown. I'm just pivoting to a cafe for now.

Victoria uses 'OOO' (Out Of Office) and dismisses David's excuse, while David uses corporate-speak ('pivoting') and the idiom 'total meltdown' (meaning a complete failure or disaster) to describe his broken heating system.
