For Penny, all the “bases” had been tagged.
She had graduated college, she got married, she had a baby, now, it was on to home plate.
She arranged for Jake and their baby meet her at work once a week to make sure all the possible predators got their warning.
When Matt wasn’t at her in-laws, there was the Nanny whom she paid very well so she’d want to be at the house as much as possible.
As for her relationship with Jake, she never argued, never made demands. She avoided sex when she could.
Her life was stress-less be because for most intents, she lived ‘alone’.
