Colloquial idioms: faces and reactions (quedarse de piedra, ponerse como un tomate)

Idioms for what your face does

Spoken Spanish in Spain is full of these images. They are colloquial: perfect with friends, rare in a report.

The verb does the work

Only the verb changes, with its pronoun if it has one (me quedé, nos quedamos, se puso); the rest of the idiom stays frozen. Quedarse and ponerse describe a sudden change, so they are usually in the indefinido when you tell a story:

When I saw the price, I was stunned.
Cuando vi el precio, me quedé de piedra.
He went as red as a beetroot in front of everyone.
Se puso como un tomate delante de todos.

Estar como una cabra always takes estar, even when it describes someone's character: the idiom is fixed. It is affectionate more often than insulting:

My uncle is nuts: he swims in the sea in January.
Mi tío está como una cabra: se baña en el mar en enero.

Getting the picture, or not

Hacerse una idea is to get an idea of something you do not know first-hand. The pronoun changes with the person: me hago, te haces, se hace.

With these photos you can get an idea of the flat.
Con estas fotos te puedes hacer una idea del piso.

Someone who se va por las ramas never gets to the point:

Don't beat about the bush, just answer.
No te vayas por las ramas y contesta.

Sin querer

Sin querer is without meaning to. It is also the usual way to apologise for an accident:

I'm sorry, it was by accident.
Lo siento, ha sido sin querer.
