Explanation:
The impersonal sentences that are formed with the pronoun are called impersonal reflexes. They are always constructed with a verb in the third person singular:
* with the verb "estar"
Example: Luego se estará más tranquilo.
* with intransitive verbs (without direct complement);
Example:
Se dice que es mejor quedarse en el hotel
* with transitive verbs.
Transitive verbs are accompanied by a nominal element, the direct complement, which indicates person or thing. The impersonal sentences that are formed with a transitive verb always have as a direct complement a person preceded by the preposition "a".
Whether the direct complement is singular or plural, the verb must always be con-jugated in the third person singular.
Example:
Se entrevistó a un empleado de aquella oficina.
If the direct complement is a thing, then it is not an impersonal sentence, but a reflexive passive sentence, where the subject of the sentence, the patient subject, is the nominal element that accompanies the verb and always has to agree with its in number.
Example:
Se vende la casa de los abuelos de María.
