2. Repetitive conversational behaviour, always wanting to talk about a specific aspect or topic, unable to let it go until a sense of satisfaction has been attained.
As the conversation goes over how to approach a girl someone mentions that women nowadays are super-independent and that this is to be respected. John starts extranerding and can't let go of the issue. All night he discusses how this came to be with the women he talks to. He goes over statistic facts, political agendas, the socio-economic status of different stratas of female groups in the western world relating to historical events in modern and industrial time. This unevitably creates a difficulty for the women to interact with John, as he while continuing his social interaction is still actively processing this issue.
