Not at all, honestly. If I was a parent (which I would never be, even if I was straight or had money for adoption, cause it's selfish to bring innocent souls into this disgusting reality and then have expectations from them IMO), I wouldn't once expect my child to take care of me and wipe my ass once I'm old. I'd even feel incredibly guilty if they felt it's their responsibility. Cause it's not. Children don't choose their family, they can walk away and never look back if they want and no one should shame them for it.
My mom can go fuck herself. I think there will be at least one of my brothers to take care of her, but I don't give a fuck. After my youngest sister was born she started being very abusive so I certainly hope she's smart enough to go far far away from here once she's 18. You didn't care about us we don't care about you, it's just how it goes.
