Will it take the rest of my life to process what has happened? I don't know.If Freddy were here, he would say, 'Yet', as per the rules of a playful accord we have concerning unacquired knowledge, whereby if one of us said they didn't know something, the other had to say 'Yet'. And then the other one--usually me--would provide the missing information, or we'd look it up, or just speculate.
