I’m not gonna teach my daughters who they are or are not supposed to trust. Because I will never teach my children what they should think, but rather how to think for themselves. I will encourage them to only trust individuals that prove themselves trustworthy, but again, that’s not my decision to make.
They’re not extensions of me; they are distinct, individual human beings. So I certainly hope you will not teach her to be distrustful; that leads to misery and pain, all in the pursuit of something that doesn’t belong to you and never will (her mind is her own, whether you like it or not).
