Why would the mum need to earn extra money by selling herself? The daughter has already gotten a acting-manager's business card, that's already like the biggest hurdle over-come isn't it?
Or are we going to get some dumb acting classes arc where the mum desperately tries to send her to an expensive school?
Also, try imagining this exchange from the mother's view:
"Do you want to be an actor? "
"I'm sorry"
Starts weeping uncontrollably
"I'm sorry I'm sorry I'm sorry I'm sorry I'm sorry I'm sorry I'm sorry"
"???!! Holy shit STFU!"
