Not all parents deserve to be parents

Looking at the small house where she saw Grace stopped, a shallow breath slipped past Penny's nostrils. 

'Grace is such a horrible liar,' she commented in her heart. 'Why lie about her childhood? It didn't seem like her mother left her be.'

It was an irony that when Penny was still a free woman, she didn't have people whom she could call her friends. Even her colleagues weren't her friends. But when she got into prison, somehow, she was able to call people her friends — some, even family, like Grace. 

Grace was akin to her sister; they were cellmates halfway through Penny's sentence. 

And in a place like the maximum prison, they could either talk to each other or fight or get thrown into solitary confinement.
