Inclusion of "lui" in answer.

Question

I am puzzled by the inclusion of "lui" in this question. The question was "You had been able to say goodbye. A possible translation is "Tu avais pu dire au revoir"

Accepted Answer

Hi William,
In the lesson , I think it is, "Tu avais pu leur dire au revoir....".
It is just , "You were able to say goodbye to them..." rather than just to say goodbye as you suggest. Just a bit more precise.
Hope this helps!

Answer

I am not sure what your question is. Maybe it's this?
Tu avais pu lui dire au revoir. -- You had been able to say goodbye to him.
-- Chris (not a native speaker).
