Greetings before a Conversation
Sometimes you stop and talk for a minute as you say hello. This type of greeting is followed by a conversation. Close friends often hug when they greet each other, especially after a long time without seeing one other. Men sometimes give each other a hand shake or a high-five (touch palms above the head).
Pair Practice (casual between friends or coworkers)
Listen and read:
A: Hi Corey.
Note: Between very close friends it's uncommon to use names in a casual greeting. Sometimes nicknames or short forms are used. (Cor and Jen instead of Corey and Jennifer).
