"So you said something the other day that's been bothering me..."
The other day being two weeks ago and you're like "Wait... You've had that on your mind and were acting like nothing was bothering you all this time?"
Sometimes I'm happy that I don't hold grudges/forget the things that bother me quickly, sometimes I wish I remembered better so I could bring back shit from the past when I get accused of something... It wouldn't improve the situation but at least I wouldn't be the only one feeling bad!
Edit: One thing though, the meme could have used "them" instead of "her" because I've known people who act like that from all genres and with any type of relationship with the person getting accused.
