You make an appointment with several days or a week notice. Although you have a scheduled appointment, you are requested to call and confirm either that day or day before. What is the purpose of the confirmation call? Since my days on ASPD, some women require one and others do not.
Is it a sort of Point of No Return? Can either party cancel the appointment without any ill feelings toward the other? Thus, both parties can attempt at another time without prejudice.
Is it merely a reminder so both parties know of the upcoming? The assumption is that cancellation is not an option.
I've owned either a Palm, Treo or iPhone for years. So, I never needed a reminder when I was supposed to meet someone.
