Getting over a crash

[Sean]

What's the best way to get past the mental issues that come with a crash?

First time the girl rode, she crashed pretty good. Hand slipped off the clutch and goosed the throttle when she rotated her hand to grab the brake. Bad news all around.

Now, every time she gets on the bike she's petrified. Literally shaking.

Tips?

(yes it's about a dirt bike but I figure this is more fitting in the street section)
