Questions & Answers about Habíamos guardado las entradas dentro de la cartera, pero fuera estaba lloviendo.

Why is it Habíamos guardado and not Guardamos?

• Habíamos guardado (pluperfect) marks an action completed before another past reference point. Here, storing the tickets happened earlier; the rain is the background at that later moment.
• Guardamos (preterite) would simply state a past action, without highlighting that it was already done by the time it was raining. Both can be correct, but the pluperfect adds the idea of “we had already put them away.”

Shouldn’t the participle agree with las entradas? Why not guardadas?

• With haber (compound tenses), the past participle is invariable: habíamos guardado (never guardados/guardadas).
• Agreement appears with verbs like tener when the participle behaves like an adjective: Las teníamos guardadas en la cartera (here guardadas agrees with las entradas).

Could I say Hemos guardado instead of Habíamos guardado?

• Hemos guardado is present perfect (linked to now). It doesn’t match the rest of the sentence, which is set in the past (estaba lloviendo).
• You could say: Hemos guardado las entradas en la cartera, pero fuera está lloviendo if you’re speaking about the present moment.

Is dentro de la cartera different from en la cartera?

• Both are fine. En la cartera is the default “in the wallet.”
• Dentro de la cartera explicitly emphasizes “inside,” and pairs nicely with the contrast fuera (“outside”) later in the sentence.
