When the twins asked me why I was so happy all the time I explained to them how my birthday was coming up, they got really excited and told me that we had to celebrate. So as they were planning my surprise, I tried to talk to Hermione about the giant dog but she refused. When I tried to get her to come with me to talk to Harry, she just walked away without a word. Without her I didn't want to talk to Harry so I decided to forget it.
