in reply to OO-style question

If B doesn't seem natural responding to A's methods, then B is not an A, and you can't use inheritance. So more likely, B "has an" A, and some of B's methods will be implemented by delegating those to the A instance within B.

But that brings back an odder question. Are B and A really both subclasses of the unnamed base class? Perhaps that's where your problem is.
