Typo here, the correct would be:

Thanks Hari, that clarifies all a bit more!
Anyway, I have more questions if you don't mind :)
1) How can I call DontOverrideMe by a the Father reference?
2) How can I do the last thing questioned, but with reflection? (I mean,
instead of oSon.Method, with something like oSon.GetType().GetMethod(...)...
3) How can I avoid declaring a GrandFather class (now I am using it
because otherwise I am unable to use the sealed keyword in a method).
