Emphasises that something happened abruptly or without explanation or ceremony. The repetition ('así sin más') intensifies the sense of abruptness. Very natural in everyday speech across all ages.

Idiomatic expression meaning to fully guarantee someone's integrity or reliability. Implies personal risk to one's credibility. Usually appears in positive or negative constructions ('pondría la mano en el fuego por él' / 'no pondría la mano en el fuego').

Idiomatic phrase meaning to keep a secret until death, never revealing it. Used to express that information died with a person or that someone intends never to disclose something.

Stock phrase used to console someone after a romantic setback, or more broadly to suggest there are many other options. In this dialogue it is used wryly with a follow-up twist ('pero pocos atunes'), showing it can be played with for humour.

Describes obsessive or circular thinking, usually about a worry or unresolved problem. The subject of the thinking is introduced with 'a' ('darle vueltas a algo'). Very common in spoken Castilian.
