In my junior year of high school (1999-2000) I dated an Asian chick who was adopted by a Mormon family. I remember her family refused to drink any beverage with caffeine but that her little brother could drink Caffeine Free Mountain Dew (gross).

I remember she couldn't come to my New Years Eve party because her family was hunkering down for some scary event. Did the Mormons have some sort of end of the world belief for the year 2000? Or was it just Y2K nonsense? I never asked because her quirks were too much for me (although she was damn cute) and we broke up.
