Somewhat the opposite. My mom started "borrowing" money from me when I was a teenager. I was too trusting, but eventually i learned to say "no".
Fuck, I haven't thought about any of this in a long time. My mom was awful.
Edit:
I forgot to explain why borrow was in quotes. Most of the time I never got paid back. I still believe she intended on paying me back, but was never able to get ahead financially enough to do it. In general if she borrowed less than $100 she'd get it back to me and pretty quickly. Over $100 it would take her too long to save it up and she'd forget about it.
