It’s an expired pin number. I’ve had no problem remembering it years after its redundency, so maybe you’ll rember it. I used to think as it as “Thor ate Tusiks”; Tusiks is made up, but Thor is the Norse god of Thunder and probably had quite an appetite.
Alright then I’ll take 0219. Though, I’ve never once been on a phone in my dreams before, and when I am near where one is supposed to be, it’s usually gone. Someone be sure to make it ring loudly.
