Ah, the mythical "quick call" that's about as quick as compiling a legacy C++ project. The innocuous "you have 5-10 min for quick call?" message that somehow warps the space-time continuum and turns into a 35-minute existential crisis about project deadlines, scope creep, and why the intern broke the production database again.
This is why I've developed a sophisticated algorithm for estimating meeting durations: take whatever time they suggest and multiply by π. Works every time. Now excuse me while I go block my calendar for the rest of eternity.
