G: Who else is going to be there?

H: I'm inviting you, my sister, and several friends from work and school.

G: Your sister? She is such a party animal. She parties really hard.

H: Yeah. So you needn't worry sitting there by yourself.

G: Exactly! I really hate to be a wallflower again. It's so awkward!

H: Believe me, it won't happen.

去别人家参加聚会可以事先问一下相关信息，例如有哪些人会参加，需要做何准备等等。对话中使用的party animal特指那些“聚会狂”，逢场必到。而wallflower可译为“壁花”，指那些在社交场合因羞涩而受冷落的人。
