NOW are you happy,
The OP never said she hates her father; she said she hates when her father spends so much time on his phone. Obviously she loves him, or she wouldn’t care to spend time with him. Personally I think it’s very mature of her (especially given that she’s 13) to vent her feelings on this forum & get some helpful advice about how to make her points in a respectful way. This allows her to express her negative feelings anonymously without offending or embarrasing her father so she can communicate with him constructively later.
I think the previous posters who suggested that she discuss this with her father in a respectful way, or bring it up at the end of a conversation, made good points in a way that Dale Carnegie would.
I’m not sure what posts by mdlevine you are referring to–neither of his posts seemed negative to me, and I’m not sure what letter you’re referring.
