Line from the movie "Coco"
I am trying to study Spanish with the movie "Coco."
Close to the end, when Miguel is talking to Mama Coco, I think he says
"Mama Coco, mira.. No lo fallas olvidar."
Which (I believe) means "Don't forget him."
How is it different from "No lo olvidas"?
And please give some examples of how the word "Fallar" can be used with other verb?
Thank you in advance!
