The most important thing you will need to learn is what to say when you are at the party.
In order to be liked, it doesn't matter what you look like, or how much money you have. Although both of these help, the most important thing is if you are a fun person. Usually, fun people have good things to say and keeps the conversation going. You can engage in small talk, but it also doesn't matter what you say, it matters how you say it.
The most important thing to do is to do a lot of laughing. It really doesn't matter what you say, so no use learning new sentences. I will have several practice sessions so you can hear what the conversation should sound like.
