Spanish language Q&A Forum

In your example on the use of tanto...como, one of your sentence  has left me uncertain about the translation. Tanto cuando son pequeños como majores, los hijos siempre preocupan a los padres. The English translation in your example is: Whether they are young or grown-up, children are always a worry for their parents. The use of the personal "a" before the word "los padres" suggests that the children worry about the parents, except that the verb should have been "se preocupan"..If it was intended to mean that the parents always worry about the children whether young or grown-up, in my opinion, the words "los hijos" and "los padres" should be interchanged, with the verb se preocupan. Otherwise  " están ocupados" should have been used instead of "preocupan"  and or used before los padres. Please advise.

In English, we also say that a book is "heavy reading" when the subject matter is academic or complicated and detailed.  A subtle difference between heavy reading and difficult to read.  A book might be difficult to read if it is badly written.  Not quite the same as "heavy reading"

Does the same subtle difference exist in Spanish?

How does one determine whether to use "sido" or "estado" with haber in such instances as "I have been a good person..." or "I have been seen with ..." or "I have not been trying hard to..."?

Also, with regard to "he, has, ha....etc.", is this conjugation referred to as the present perfect indicative, the past perfect indicative (preterito perfecto), or both?
