"Oh, for Merlin's sake," Severus said with disgust. "Are you always this melodramatic? Sit down, idiot boy, and stop being foolish."
"Being human and normal is not the same as being a burden," he said acidly. "You would only be a burden if you were sitting around, whining and doing nothing to help in this war. I am sure that if Miss Parkinson did not care about your problems, she would let you know. She has never been shy about expressing her opinion. Don't try and put words, feelings and opinions in her mouth unless you know that they are true."
She smiled mirthlessly. "And I am sure that you know that I would tell immediately if I thought you were being a burden. You are not. You are being foolish and stupid. The entire world does not rest on your shoulders and it is sheer Gryffindorish arrogance to think that it does. What Albus did to you was as much a crime as what your relatives did."
