gfvalvo:
I’ll try to come up with a more concrete example.

I want friends, but I want them to be nice guys (I'll befriend a dunce, too).

If someone is a Big Jerk, I've got to change them before I let them be my friend:

enum HumanTypes{
  NICE_GUY,
  BIG_JERK,
  DUNCE,
};

class HumanBeing{
  public:
    HumanBeing(HumanTypes _type){type = _type;}
    HumanTypes type;
  private:
};

class MyFriends : public HumanBeing{
  public:
    MyFriends(HumanTypes tp) : HumanBeing(tp == BIG_JERK? NICE_GUY : tp){}
    void getFreindType(void){
      switch (type)
      {
        case NICE_GUY:
          Serial.println(F("Nice Guy"));
          break;
        case BIG_JERK:
        Serial.println(F("Big Jerk"));
          break;
        case DUNCE:
        Serial.println(F("Dunce"));
          break;
      }
    }
  private:

};

MyFriends tom(NICE_GUY);
MyFriends john(BIG_JERK);
MyFriends billy(DUNCE);

void setup() 
{
  Serial.begin(9600);
  tom.getFreindType();
  john.getFreindType();
  billy.getFreindType();
}

void loop() {

}

now that he's my friend, john is a nice guy!
