Why does a callable bond break the normal duration shortcuts I use for straight bonds?

I understand modified duration for fixed cash flows, but I keep missing questions where yields fall and the callable bond does not gain as much as I expected.

The shortcut fails because the bond's expected cash flows are no longer fixed. When yields fall, the issuer becomes more likely to call the bond. That shortens the expected life and caps some of the upside price gain.
