Thanks for this sunshine. Use a metaphor from the common cultural experience of the people with whom you are talking. For the brain to catch and retain a detail, that detail must hang on one of the memory-inducing hooks that is already in the brain. Or relate your topic to the listener's work situation or work with which she is familiar. People also remember landmark places where they live, have lived, or have visited or well-known places.
Motion makes memories.
Whenever people are moving or see movement, they remember more and are more emotional about what they remember. Get customers in motion with you in a positive experience and they will be more fervent, vivid, and believing fans, more likely to evoke their bragging rights and likely to share their experience with others. That's why we literally move to offer samples, getting people to reach out, so they feel the experience more deeply. An experience is most memorable when you and the other person are both in motion, such as when you shake hands, walk together, or reach to exchange something. Pick those ripe moments to say the most vivid, specific detail you want the listener to remember and repeat to others.
