All of my life my mom was a serious Coke  drinker.  She could easily beat that stupid Pepsi  challenge. If she came to your home, even for a short visit, she would have two things with her: a liter of Coke  and her green cup.   This Green Cup  was the holy grail to us kids.  For some reason,  didn't taste the same unless we took a sip out of it.  It was grimy.  Without shame, mom washed the cup probably only once per week.  She said it was her cup and that she had to let the Coke  set in it.  And we didn't care.  From my generation to the next, we felt it was an honor when mom, Grandest, or Aunt Charlotte would say, "Go fill up my cup!"   All that meant was - WE DRINKING SOME COKE FROM THE CUP .       ignore the lack of dusting. :/  Mom knew.  She would joke and say, "You didn't drink any did you?" Every kid would swear they didn't but we all new - we couldn't resist.  So where is the infamous Green Cup  today?  ...
