How to be polite when meeting someone: Five “Always” and Three “Never”. 1. Stand, smile and shake a hand in greeting. 2. Introduce the younger person to the older person. Say the older person’s name first. 3. Use an adult’s title and last name. 4. When you know it, include a little description (for example) that helps people understand the connections. 5. Make the introduction even if you’ve forgotten the person’s name. 6. Look at the ground or away when you are being introduced to someone. 7. Refuse (or take a long time) to shake a hand extended in greeting. 8. Shake someone’s hand in a bone-crushing grip (very hard).
