Sometimes it is better not to know. Sometimes when you do know you just fold up.

There are things you don't want to know you can do

Stop it. This is me, remember? We've been thrown up by the same puppies. - Ossin

Cats were often familiars to workers of magic because to anyone used to wrestling with self-willed, wayward, devious magic--which was what all magic was--it was rather soothing to have all the same qualities wrapped up in a small, furry, generally attractive bundle that...might, if it were in a good mood, sit on your knee and purr. Magic never sat on anybody's knee and purred.

What we can do, we must do: we must use what we are given, and we must use it the best we can, however much or little help we have for the task. What you have been given is a hard thing--a very hard thing... But my darling, what if there were no one who could do the difficult things?

As I have said, you have no reason to trust me, and an excellent reason not to.
