Joey,
Thank you for the explanation. Sorry, I tend to get carried away sometimes. I'm not sure what polar bears would have to do with anything. I thought maybe since he would probably be lonely in Canada, he would need some companionship. And polar bears do snarl quite loudly (so I've heard) so they'd be able to keep up with Professor Snape's moods.
Well, I'm going to see if I can finish studying before bed.
