Frankly, I think that one is classic projection and deflection. Translated it probably means "I think it will be too hard for me if you see her." But it's much nicer and "selfless" to say that I think I'm being nice to you by saying no to you. It keeps them from taking the responsiblity of the decision, and also puts them in a falsely parental and nurturing position over the bparent. If it's too hard for you, or it's too hard for your child, then say so. But don't judge what's too hard for someone else.

I'm not saying that aparents don't have a right to say no to requests if they have a truly valid reason, I just don't think that deciding for someone else what will be "too hard for them" is a valid, or honest, reason.

So basically, yeah, I think that one should never be said.
