Virtual or override, correct.  You must specify this to tell the compiler
"yes, I meant to override this" the same way you use the new keyword in that
context to tell the compiler "yes, I meant to hide this."

You don't need to use override to implement an interface method since there
is no implementation that you are overriding.  (Though using this logic you
could make the case that you shouldn't need the override keyword when
overriding an inherited abstract method.)
