4. Remind them that the world does not revolve around them.

A self-absorbed person might just need a little reminder that the world does not revolve around her. Speak up and tell her as much without coming across as if you are attacking her. For example, instead of throwing a tantrum and screaming, “You never listen to me; you always make everything about you,” try saying,”I really need to talk to someone about something bothering me. Would you be willing to listen to me?”
