It is polite to greet many people at a social event. This is called "mingling". After you greet people you know look for people you haven't met before. Introduce yourself and start a conversation.
Say hello and introduce yourself to a person who is not in a conversation.
Talk about your relationship to the host.
Discuss one party related item (food, theme, length of stay).
Who are you here with?
How do you know Jane? (party host)
I don't think we've met.
Have you been here long?
Have you tried the cheese dip/dessert/punch?
Where did you get your costume?
The food looks great. I can't wait to try the dip.
I love your dress/shirt/hat. It really suits you. (looks good on you)
These decorations are wonderful. I love the table cloth/balloons/flowers.
Listen and read:
A: I don't think we've met. I'm Stacey. (hold out hand to shake) B: Hi Stacey. I'm Carl. A: Hi Carl. So, how do you know Jane? B: Oh, Jane and I used to work together at a coffee shop. A: Oh, you mean when you were working in Japan? B: That's right. And how do you know her? A: Actually, Jane is my cousin. Our moms are sisters. B: No way! You two don't look anything alike.
