Pre Goodbye’s are needed to make sure the goodbye comes within minutes not hours. They are used when you go to a party or event with another person who doesn’t appear to look at an clock. For by the time the other person actually is ready to step out the door someone else might just call them in. Pre-Goodbye’s allow you the time to acknowledge to everyone around that you plan to leave even if your partner is still saying hello. Pre-Goodbye’s give you the peace of mind to just walk out.
