Gaston has been shown to be a very straight-forward person. At beginning we see how clearly he mentions that he is by no way interested in spending a fortune on buying a villa in which his wife’s parents could stay. He is also an opportunist as he takes advantage of the situation to break a great deal and earn a hundred thousand francs of it. He earns this huge profit which shows that he is a better and cleverer business man than Juliette.
Juliette seems like a very hard core business woman who does not budge an inch in her decision of selling the villa and its price. She,at the beginning of the play, seemed like a very helpless woman who is in dire need of money and wants to sell the house immediately.
