1) Start out by mentioning a neutral landmark, like a robot (traffic light). Ex: "Go to the robot." Do not identify which traffic light you mean.
2) First say to make a left, then later on when the directions need clarification, say right. Agree with whatever direction the person seeking directions suggests.
3) Refer to a recent neighborhood event to explain where you mean. Ex: "Where those men are working with the trucks."
4) Mention a landmark that is actually useful, like a major intersection or shopping center.
5) Explain that the person seeking directions should go there and ask someone else for directions.
