Suddenly a lady comes up to the pair and interrupts their conversation awkwardly and begins talking in a disrespectful manner. This throws the men and then results in ruining the conversation and loss of communication.
By ruining the conversation it results in awkwardness between the three characters a way to avoid was for the lady to briefly interrupt and respect the conversation taking place and her actions toward it.
