I'm trying to write a sentence but can't decide which is the correct form:
For anyone who didn't notice, he is tall.
For anyone who hasn't noticed, he is tall.
For anyone who hadn't noticed, he is tall.
I think the third one is incorrect because there aren't 2 actions happening the paat one after the other.
I am doubting between the first two. There is no specific time so "hasn't" should be correct, but I can't see why "didn't" isn't correct either.
Truly, I have no clue how to decide.
More Context:
If it matters, the context is a friend wants to post a pic in twitter of a group of friends, and jokingly say on one of the friends "For anyone who didn't notice, he is tall".
