Maybell, your daughter probably feels safe to be snotty with you, which you could take as a sign of her trust. She knows your love is unconditional, so she can be free to express her (sometimes difficult) emotions in that way. My daughter shares her sadness (but also her snotty teenage angst) with me, but not with H because she doesn't feel safe sharing her feelings with him.
