When you're in a group of people, for example three persons and there's two of them you know well. The third one you haven't really been talking to but when you have to go, you hug that person too so it won't get awkward.
Yesterday I was talking to Matt and Emma, Lisa was there too. I had to leave, and hugged them, I gave Lisa a courtesy hug.
