the most interesting exercise i've ever thought about

Find a vector field Y over a manifold M (if possible I'd like M = |R^n )
such that Y vanishes along a fixed direction X but whose Lie derivative
respect to the vector field constantly equal to X doesn't vanish along X.


Thank you very much for any help.
