How would you explain ‘Posadas’ in the context? “What about you? That girl came in the shop again last week. This is the Rebeca I told you about, the friend of that little jelly bean you took to the Posadas last winter, and if you ask me, this Rebeca is ten times prettier. If the other one is a wet sock, that’s your good luck. She was a half-portion, if you ask me. But the friend is really swell.” How would you explain ‘Posadas’ in the sentence: the friend of that little jelly bean you took to the Posadas last winter? Thanks!
