This epitomises Jack's narcissism. Her fellow AA-er, who presumably thinks of her as a friend, is reduced to "one random woman".
Then follows tweets about herself and how terrifying she finds phone calls but despite this how enriching she finds it.
Then her "hustle" about how to start the conversation so she can have an opening to talk all about herself! And is childish and narcissistic enough to think her droning on about herself is somehow deepening their relationship and beneficial for the recipient.
She doesn't care about this random woman, at all. It's all about herself and her needs.
