Is there way to draw a self referencing object in UML?

For eg: - I have an automated answering system. There are parent
messages and Child messages for each message.

How can I represent this in UML?

Thanks,
Ann

It depends one where you are. In a class model relationships define
static structure and not participants so a reflexive relationship (i.e.,
connecting the entity to itself) is not sufficient for what you want. In
an Object Diagram, though, one identifies specific objects so a
reflexive relationship does express what you want. In an Interaction
Diagram one can identify specific objects in swimlanes and a reflexive
message is legal.
