In Ruby, the *overriding* actually is *shadow* the superclass's method
(hope that I used right word). You can't direct call the superclass's metho=
d
but it still around, it don't be removed.

When you call super, it'll go up in the class's
inheritance tree step-by-step
and find method with same name.
(sorry for my bad English)
