Friends. I started watching Rick and Morty with English subtitles, but English is not my first language, and I have a problem in understanding the meaning of this Dialogue. Beth says it to his father that caused Beth's son didn't go to school the entire semester.
Beth: “How could you make my son miss an entire semester of school? I mean, it's not like he's a hot girl. He can't just bail on his life and set up shop in someone else's.”
I didn't understand the meaning of "He can't just bail on his life." and "set up shop in someone else's." I understand the general meaning of the sentence, but I didn't get the exact definition of "bail on his life" and "set up shop in someone else's." I think these are Idioms that I couldn't find the definition of them.
