Dragons don't see the point of celebrating some measly date every year, especially when they can live up to thousands of years. Or at least, Crematia doesn't. Those pathetic metallic dragons might, they are pretty soft-hearted enough as it is.

"I don't see the point of that. You ought to be celebrating the anniversaries of your accomplishments, not the day when you are hatched." of course she wouldn't do that either, but she can understand why lesser beings would do that, at least.
