My sister and I were at the mall and passed by a store that sold a variety
of candy and nuts. As we were looking at the display case, the  boy behind
the counter asked if we needed any help. I replied, "No,  I'm just looking
at your nuts." My sister started to laugh hysterically, the boy grinned,
and I turned beet-red and walked away. To this day, my sister has never let
me forget.
