This iconic meme is sourced from the 2019 blockbuster 'Avengers: Endgame.' It features a poignant exchange between Wanda Maximoff (Scarlet Witch) and a time-traveling 2014 version of Thanos. After Wanda declares, 'You took everything from me,' Thanos coldly responds with, 'I don't even know who you are,' highlighting the emotional gap between their shared histories. The format quickly went viral as a way to mock situations where someone’s intense personal grievance or obsession is met with complete indifference or a total lack of recognition by the other party.
