# Zeroth dimensional relative Morse Homology vanishes

Currently I am reading Morse Homology. And I faced a problem, which is easy to show in case of Singular Homology. But I can not do it for Morse Homology.

So the problem is, for any submanifold $$V$$ of a manifold $$W$$, the zeroth dimensional relative Morse homology $$HM_0(V,W,\Bbb Z_2)=0$$.

Any help will be appreciated.
