The magic of Tango

The magic of tango divides into two parts. Those spells whose design it is to entrance the audience and those spells whose design it is to entrance the dancers. For some bizzare reason people have become convinced that those spells that will wow the crowd will have the same effect on their partner. Why? They do not attempt to entrall the crowd with spells intended only for their partner. Why should their partner be entralled by spells not meant solely for them.
