Conclusion: Coordinate all appointments properly with Yellows. Synchronize your watches. Explain very clearly that the plane takes off at 8:00 P.M. and that if he doesn’t show up by then he’ll be left standing at the gate. Say it like it is: If he’s not in his car outside your door two hours before the plane takes off, you’ll drop down dead of a heart attack. Tell the Yellow that you will be deeply irritated with him and that your friendship could be damaged due to his continual slipups.
