LORELAI: You need to develop a defense mechanism for dealing with Grandma.
EMILY: What are you talking about?
LORELAI: You just need a system, a new mindset.
Faced with Emily’s mounting hysteria at the prospect of Trix seeing Lorelai’s house and workplace, Lorelai gives Emily some advice in dealing with Trix. Instead of feeling hurt and upset by Trix’s criticisms and putdowns, she should find amusement in them – perhaps even encourage them. Lorelai is frank about the fact that it is how she copes with Emily’s criticism and hurtful comments. Although taken aback, Emily does actually take Lorelai’s advice on board, and puts it into practice that very night.
