I'd appreciate it if someone would answer my questions. Thanks in advance.
Concerning the sentence: I regretted that I hadn't been kinder to her while she had been still alive. (Sorry no context)
In the "that clause, Past Perfect is used both in the main clause and the subordinate clause.
What I want to ask is the following 2.
Where is the reference point, the time I regretted or the time she died?
I think "were still alive" is better than had been still alive. What do you think?
