That's very different from object A calling a method of object B which
in turns invokes methods on object A now isn't it? What the OP
described can be more aptly called the prostitution design pattern.
Object J has a need that it cannot satisfy, so it visits object H to
get its private part operated upon. It's sick. It's immoral. Objects
should only play around with their own thingies.
