The E key has been the universal "interact" button since the dawn of PC gaming. Press E to open door, press E to pick up item, press E to pay respects. It's muscle memory at this point. But then tactical shooters showed up and decided F should be the lean button. Now you're standing in front of a door, instinctively mashing E like a caveman, while your character just tilts sideways at a 45-degree angle looking like an idiot. Meanwhile, the actual interact key is F, sitting right next to E, mocking you. Game devs really looked at two adjacent keys and said "let's make players choose their personality type." You're either an E person living in peaceful adventure game bliss, or an F person who's been scarred by Rainbow Six Siege and can never go back.
