Spanish language Q&A Forum

I would like to ask if this construction is often used in Spanish. Is it in some cases interchangeable with cuando? Can it also mean immediately after? E.g. : al regresar del museo me tumbé en la cama? Al plus infinitive seems to be a very convenient construction.

Does it have to be a specific duration with desde hace? Or could we say:

No visito desde hace mucho tiempo un pueblo tan bonito que este

And would it be incorrect to say:

Ha pasado mucho tiempo desde que visité un pueblo tan bonito que este.

...or is it just another way of saying the same thing?

Why is the (se) in parentheses in the title of the lesson? Every example is reflexive. Would one ever use a non-reflexive quedar in this context? (If not, it seems like the parentheses aren't needed, no?) 

Hello and I hope you and yours and the team are all doing well.

Re: This lesson;|
Would it be safe to say that this comes under the umbrella of the "passive" and if not, why?

Thank you!

I understand the lesson well.However, I want to ask whether one of your sentences could have been written better.', incorporating  "Lo" from a previous lesson.. Su oración en español fue: Ayer, estuve pensando en cómo nos conocimos. Pues, yo no me  acuerdo.  ¿  lo podía ser mejor si usáramos : ...Pues, yo no lo acuerdo?
