A little girl standing in the middle of a street cleared for an oncoming parade.
A small girl is in the parade for the marching band.
A little girl standing a cleared road for parade does not make her participate in the parade band.
Being in the street during a parade does not necessarily mean that someone is in the marching band.
Little does not imply small. Standing in the middle of the street does not imply she is in the parade or in the marching band.
