cannot do something: actual state must match

Just fill in "do something", "actual state"

* Exception
that happens at a lower level on the call stack,
* use the pattern:
cannot do something: <
* exception.getMessage()
>.
In practice,

* can do about it except making sure that if your own
* Exceptions
have a useful getMessage()
.
