Your brain actively rewrites your memories every time you recall them, meaning the more you remember something, the less accurate it becomes.
In short we are all delusional
So my dad has been ending every phone call with "stay dangerous" instead of "goodbye" for like six months now. We all thought he was just being a weird dad. Turns out he's been mishearing the ending of a podcast he listens to. The host says "stay curious" but my dad is slightly deaf in one ear. He's been going around telling his coworkers, my grandmother, and apparently his DOCTOR to "stay dangerous" this entire time. My mom only found out because his doctor called to check if everything was okay at home. My dad has now decided he likes his version better and refuses to stop. Yesterday he told a nun to stay dangerous.
In the original Heat screenplay, when Neil McCauley realizes that he and his crew are under LAPD surveillance, he has them regroup at their usual diner, but Michael Mann instead chose to shoot the scene outside the La Fresa Electrical Substation – for a very specific reason.
That substation is basically a giant electrical junction box for the city. It takes in extremely high‑voltage electricity from transmission lines connected to power stations, then redistributes it through the local grid. In the process, it generates so much electromagnetic interference that it can scramble any listening devices that might have been planted on the crew or their cars.
