Acknowledgment

Take the time to call and thank your appointments for the time that you spent together. Remember to mention something that you discussed. Try to come up with something that you can offer them, whether it’s a lead, a Power Partner or information about an event.

You could probably count on one hand the number of handwritten thank you notes you received last year. When someone takes the time to give you a referral or to have a meeting with you, make sure you return the courtesy with a note.
Invitations

When you receive an invitation, please respond in a timely manner. Don’t wait until the day of the event. Immediately put it on your calendar so you won’t forget or double-book yourself. That way you’ll be sure to show up for the function.

People put a great deal of effort into planning an affair. Part of the planning  involves trying to figure out how many people will attend so there will be enough food. So not attending after responding can turn out to be just as rude as not responding at all.
