Which of the two is more appropriate, and why?
But in what cases and how?
Well I watched a show where a FBI agent meets with a disgruntled agent, the said agent says to him: "I gave you everything I had and you people betrayed me."
I was wondering why it wasn`t ÿou people have betrayed me"
But is it wrong if it was used?
That answer wasn`t satisfying.
In this case, it's probably simple parallelism. "I did this, and [in return] you did that." Not, "I did this, and you have done that."I need more explanations on why that is the case.
Thank you very much!!!! ))
