It can be very obvious when someone is lying, so when you figure out that someone is lying, call them out on it. Let them know that you will not take their lies and that they had better tell you the truth. You can be direct and demand the truth be told, or, depending on the person, talk to them with a leveled tone so that you do not scare them into lying to you further. Try to be understanding and figure out why they lied to you in the first place.
