I don't seem to be getting this lesson. I freely admit there are things above my head. When I just don't get it, I want to move on to other things (to stay motivated) hoping sometime in the future I'll get it then. Sadly, I am stuck on a subject that I won't even use much as a beginner. I'd like to skip it.  Just my opinion. Thanks. 

Would it be more correct to change this sample sentence:
 "Puede que yo haya sido un poco brusca, pero tenía que decir la verdad."

Vs.

"Puede que yo haya ESTADO un poco brusca....."? \

Thanks for your input. 

In the lesson, these sentences do not make sense to me in English:

Mi vecina Clara, que es peluquera, tiene su propio salón de belleza.

why we didnt say una peluquera?

Hola Inma

In this test question: 

"Aquella chica del colegio, ________ todos se reían, estaba siempre triste"

I managed to get all these correct: de la que, de quien, de la cual. But my answer de que was incorrect.

OK, I admit that I did follow a pattern here and guess that this question required 'de' in front of the pronoun, so I actually have two questions about this:

1) why is 'de' required in this particular structure (but not usually)?

2) why is 'de que' incorrect? (but all the others require 'de')

I ask because I don't see any reference to these nuances in the above lesson

Saludos  

Hola…..¿por qué se usa el imperfecto de subjuntivo con una oración que empiece con “No sabía que_________”.  No entiendo el “trigger” en este caso.

Thank you so much for this detailed explanation Inma. It's greatly appreciated. I hope it's fair to say that I wish that  Leísmo/Loísmo/Laísmo didn't exist 🙄... another thing for my old brain to try to remember. ;))

wouldn't "on the other hand" be a better translation for: por otro lado?
