You would use a more domain-oriented design approach. Setters/getters are merely used because of all the frameworks that support (and expect) them. Why do you care where the man is carrying his pencil? Perhaps he's keeping it in his sock. All you want to do is ask the man object for a pencil. Having to go through his carrying bag to his pencil case to get his pencil is exposing the implementation. If the man exposes his bag/pencil case to the world, then someone can just steal the pencil from him without him knowing about it. However, if you have to ask him for the pencil and then he can go dig in his bag to get his pencil case to find a pencil, then perhaps he can do something at that point and jot down a note that you've just borrowed a pencil from him.
