Quasireflexive verbs also called pronominals are similar to the reflexive verbs, however, the action stays with the verb and it does not go back to the subject as a direct object. They cannot add the word a sí mismo (myself, yourself, etc.) to the end of the sentence.
The forms me, te, se, nos are not used as personal pronouns but as an intrinsic part of the verb. A few examples of these verbs are:
acostarse - to lay down
cansarse - to get tired
arrepentirse - to repent
enfermarse - to get sick
alegrarse - to get happy
Let's look at some example sentences.
Ella nunca se queja.

Nosotros nos quedamos en casa.

Los muchachos se aburrían fácilmente.

Ellos y ellas se acuestan.

Yo me enfermo mucho cuando viajo.

Yo nunca me acuerdo de su cumpleaños.
