Warm greetings can be expressed in many different ways, such as with a kiss, an aloha, or a hug. A kiss is a gesture of affection that is usually done with two people pressing their lips together. Alohas are traditional Hawaiian greetings that are used to express love and respect. HUGS are physical expressions of affection that involve two people embracing each other. All of these gestures are ways to show warmth and kindness to someone else.
