Don't be this man. One expert suggests that you never leave a message. And he also recommends that you be in control of calling. Call between the prime hours of 8 and 10 p.m. Always remember to wait before calling someone back after the initial call.
Some people practice the four-day wait and others the two or three.
Simply remember that when you call back too soon, you lose all mystery and any edge you previously had. Again, refer back to Rule No. 1 for the basis of this rule. If you've followed phone protocol, you may be looking at a first date. It may seem trivial, but where you go on your first date says many things. To start, you have to decide what to do.
