Source: game/common/character_interactions/00_perk_interactions.txt and the English localisation, Crusader Kings III 1.20.1.2. “You” is the character who sends it (scope:actor, or a puppet acting for you); “the character you target” is the recipient. “…” marks words the game fills in at play time (a name, a title).
