Ouch, I can really feel Petunia's pain, and for once understand a reason why there never were any more children in that household, in Vernon's fear of magical genes. But it is heartbreaking to see the poor child Harry suffer so terribly, and even worse that she feels she should be allowed to help him but is bullied out of it by Vernon, to the point where she believes it herself. The amount of pain in this story speaks to how very well it is written, however! Excellent characterizations.
