Personal a and direct object pronoun
Does the personal 'a' apply to pronouns? I thought the rule was that the personal 'a' applied when a person was the object of a sentence. But in the following example "when I called you (usted)" "quando lo llamé". Is the "you" not a person and an object of the verb and so should the personal 'a' not apply? I believe this question is separate from the whole leísmo / loísmo issue. I could provide other examples taken from my various grammer books.

You do not use the personal a with direct or indirect object pronouns, and if you combine the personal a with a pronoun, it will be the pronoun for an object of a preposition.
But if you do that, it is only for emphasis, and you still must use the pronoun you are referring to.
(A mí) me gusta leer. Both me and a mí refer to me- redundantly, it just emphasizes it- I am talking about me, not who we were just talking about, perhaps.
Te quiero (a ti). Again, emphasis- I love you, not someone else.
You will also frequently include the indirect object pronoun for an actual noun, and this is not for emphasis- you do not do that for direct objects:
A Pedro le gusta leer. Indirect object, so le is included redundantly without being simply for emphasis- it is required.
Quiero a María. No need to include a la as she is a direct object.
This is my understanding as an intermediate level learner.
