Words can only take you so far. All you would have are your expressions and innovation. A tad bit different from your conventional mime but scope for a lot of improvisation. One of the most loved events of the event you might want to buckle up because expectations will be high!
Only in spontaneity can we be truly who we are. It is fun and free. You are given a few minutes to act on a given situation and you cannot go wrong with this. Put your wit to some crazy use, play with words and express yourself. All of those nonsensical thoughts in your mind: yes, they will suffice.
