[puccini]

Thanks Rusty,but my problem is to understand the difference in meaning , not in the form of the conjugation .
Suppose somebody speaks to me in Spanish and will utter one of the two sentences I gave as an example in my previous post.

The speaker will chose one of these sentences in function of what he
intends to communicate .
To put it so, the two sentences, having the same denotations, (at least for me !), could have different connotations for a Spanish speaker ,agree ?
But for poor me, Preterite or Present Perfect sounds the same, I wouldn't be able ever, to say the difference in their respective meanings !
Can you make me to see the difference between the implied connotations ?

Thanks,
Puccini
