There is nothing wrong from an OOP point of view with one object
containing a reference to another object. Even in the real world, it
makes sense that a person knows where their home is.

In some languages, like C++, this can introduce some typing and API
complications, but not in Ruby where methods are invoked by sending
messages to the objects.

The problems that you might have with this approach are related to
design requirements. For example, what if one person can, optionally,
have more than one home?
