I only just now thought about the almost impossible to miss messaging of that children's book: "If you give anything to someone else they'll take and take and never stop demanding more."
Sure, that can apply in some contexts ( :porky-happy: ) but unless someone's take changes my mind about I think the message is fucked up.
I reference it fairly often at work when we talk about what to offer to do on behalf of other teams. There are definitely situations where it's simply good advice not to let people take advantage of you.
