I found this confusing.

"Hemos pedido" translates into English as "asked," which is a past tense. So I wanted to use pusiera. But the answer requires present subjunctive (ponga).

Is it always true that when the main verb is in the present perfect, the subsequent clause will use the present subjunctive? So in Spanish we should treat present perfect as a present tense, whereas in English it is a past tense?

2nd example above is  'Cuanto menos te vea, mejor'

Why subjunctive?

There is a lot to unpack in this lesson and I'm finding parts of it quite difficult to comprehend. For example, I see three forms of traer used in examples that express "we." Also examples for "can we have" that do not contain a conjugation of "poder."

Also I don't know where to find explanations of the different tenses, preteritos, etc. of both traer and llevar that are used in this lesson, so a link to the related lesson would help us out. Thank you. I can tell this was a difficult one to put together and I appreciate your effort.
