In the audio lesson on the preterite tense, an example was given of "Perdí mis llaves" for "I lost my keys". However, in Jean Yates' book "Correct your Spanish Blunders", it is stated that this should be "Se me perdieron las llaves" because it is an accidental occurrence and therefore the keys become the subject and the person is the object of the accidental occurrence. Indeed, the audio lesson used this construction for "Se me cayó" ("I fell"). Any help would be appreciated!
I've been hoping someone would answer this question for you. I asked my Puerto Rican girlfriend about this and she said she used the two examples interchangeably. She says there is no right answer here. She did say her first impulse would be to say "se me perdieron mis llaves." She disagrees with academics that say "las" should be used in place of "mis." After all, she says, one should know exactly whose keys were lost...
