Went in one ear and out the other.
Mama Bear doesn't give Sister any actual advice or think about what kinds of situations she could get into, only tells her that she has "responsibility." What that responsibility is, is never mentioned. Is this like Spider-man? Is she supposed to catch criminals?
Message
You should behave yourself at a slumber party if your mother mentions the word “responsibility” without explaining what she means.
Unrealistic metaphor that does more harm than good.
It's not bad because the message is bad, but because it fails at getting that message across and what it does get across is just upsetting.
