A year ago, a girl told her new boyfriend about her past experience with her ex. For some reason, what he heard hurt his feelings. She has apologized to him countless times, but he still can't get over it. The girl goes to a counsellor to seek advice on how to go forward in their relationship. She tells the counsellor everything, and then the counsellor says to her:
1A. It's now been a year and he's still treating it as if you did it yesterday?
The example came up in a search that I did on this website. The article in which the example originally appeared was on this website (the article is still there, but it's been edited, so the example is no longer there). I would've expected this version with "had done" instead because the counsellor and the girl's boyfriend both know that she didn't do it yesterday:
1B. It's now been a year and he's still treating it as if you'd done it yesterday?
I found a similar example on this website in which the past perfect "had been made" is used under similar circumstances, i.e. everyone knows that the paintings weren't made yesterday:
This exhibition offers a revelatory window into an extraordinarily fertile time in recent art history, yet the paintings don’t seem at all dated. Exuberantly alive to their own possibilities, they feel as fresh as if they had been made yesterday.
Did the author make a mistake, and is version #1B the correct way to say it in this context, or do you think that version #1A is correct? Thank you.
