No se te olvide y no te olvides

Question

1.Oye, Susana, no se te olvide traerme el libro mañana.

2.Oye, Susana, no te olvides traerme el libro mañana.

What are the differences between them? Or do they mean the same thing?

Answer 1

Just some additional comments to Viejito's excellent explanation:

No te olvides de traerme el libro mañana. The verb form is "olvidarse de algo".

Spanish is the language of excuses. It's never your fault. So that's why you will see expressions using the pronominal form of the verb such as "No se te olvide". You are literally saying "Don't let the book forget on you" (It's never gonna be your fault). Other examples include: "Se me cayó el vaso" (The glass fell on me) as opposed to "Dejé caer el vaso" (I dropped the glass). Se me olvidó la tarea vs. Olvidé la tarea. etc.

I hope you can get the gist of what I'm trying to convey

Let’s use some examples first…so as to understand the sentences.

A. Me olvidé las llaves. – I forgot the keys….i.e….my fault

B. Se me olivadaron las llaves – I forgot the keys…the idea is… It wasn’t my falt. It happened to me, I’m a victim of circumstance.

1. Oye, Susana, no te olvides de traerme el libro mañana.

   2nd person singular…”Te olvides “ is in the imperative command form. “Listen, Susana, don’t forget to bring me the book tomorrow.”… In other words…you are responsible…so don’t you forget…it will be your fault.

2. Oye, Susana, no se te olvide de traerme el libro mañana.

3rd person singular…”se olvide” is in the imperative command form. But the idea has changed. Listen, Susan, don’t forget to bring me the book tomorrow….It’s a command to Susan…Not to be the victim and forget to bring the book tomorrow. In other words….don’t come to school tomorrow saying that you forgot the book…but that it wasn’t your fault…that you were a victim too.

Juan, no se te olvide traerme el libro mañana. Sin DE

Juan, no se olvidas de traerme el libro mañana. Con DE.

olvidarSE de.

But se te olvide + sin de. right?

Answer 4

Heres an example of how you can use "no se te olvide":

Oye Luis, no se te olvide de traer mi libreta. No hice mi tarea.
