No, it's not. You may be the subject, but in no way is this about you. It's about how worried and scared she is for her child, and she is just angry that I don't have the power to keep you as safe as she would like you to be. It wouldn't matter if you had been trained as a Death Eating machine since birth, she would still want you in an untouchable bubble.
If you want to discuss how she feels about you being a Death Eater with her, that is fine. Or if you want to ask her why I'm not home, feel free, but you do not have the right to bring it up in the context of a fight between husband and wife.
