Hmm, interesting.
Did you know you could do this?
No, I'd never thought of it , but I guess it makes sense because it is a legal definition.
here I think:
I'd never thought of it = I had never thought of it
这我从来没有想到过,it means from some time point at past of the past to some point of the past, i'd never thought of it.
maybe now he thinks of it, but in a while from the past to a later past, he'd never thought of that.
