Her brow furrowed as Charlie called her selfish for what amounted to wanting Remus to be in the baby's life. It was jarring, and not in the way she thought Charlie meant.
"No, I don't think," she said flatly. "This isn't akin to being asked to take a position at Hogwarts, Charlie. I did that too, remember? I gave up my career, possibly for a very long time, in order to help protect these kids. I know that choice, and this is nothing like that. I'm upset about what happened with Remus because it means my son won't have a father, not because I need someone to be happy. Last time I checked, that doesn't make me selfish. It makes me a good mum. And before you go off on loving what I have instead of what it could have been, I love my son. That isn't the question. What I don't love is the situation his father put him in--put us both in. I can love the baby without loving the circumstances surrounding bringing him into the world."
She sighed, her voice losing its edge and instead growing weary. "I just want a friend right now, Charlie, not a lecture." Tonks paused and glanced at the castle. "I ought to get back. It's too cold out to linger, and I've a few things to do before dinner."
