No, I haven't. I've been too scared. But she was so cold when she came over for dinner, remember? Despite warming charms and jumpers? My brother told me to keep an eye out for the symptoms. I didn't want to say anything at the time and make her feel uncomfortable, so I just cast protection spells on both me and you. She could just have a seasonal illness, but she sent me an owl last week to tell me she'd be too sick to come to my party tomorrow. Am I overreacting? What should I do?
