if sarah pasternack were a candy, i would identify her as
a pixie stick! why, might you ask? well, the first thing that came to mind was the unescapable alliteration which makes the whole comparison a zinger...
pixie stick is sarah past backwards...almost. it's a stretch but an acceptable one.
of course, i am referring to the really small pixies and not the giant ones. the small pixie sticks match her size and frame; observe:

i loved pixie sticks as a child; especially the blue raspberry flavored ones...
i wish they were more commonly found in grocery stores these days.
do you ever wonder what kind of candy you are? well, then tell me and i will try to find your match!
no guarantees that the match up will be as perfect as sp to ps...but i'll give it my best shot.
