“Apart from my transformations, I was happier than I had ever been in my life.
For the first time ever, I had friends, three great friends... I was terrified they
would desert me the moment they found out what I was. But of course, they,
like you, Hermione, worked out the truth...and they didn't desert me at all.

abnormally large nose out of other people's business.
Mr. Prongs agrees with Mr. Moony, and would like to add that Professor Snape is an ugly git.
Mr. Padfoot would like to register his astonishment that an idiot like that ever became a professor.
Mr. Wormtail bids Professor Snape good day, and advises him to wash his hair, the slimeball.”
