How to convince parents getting you Get Together for Christmas?

I'm a disabled adult, and my parents don't mind that I play The Sims because it can teach you about life. Your Sim has to gain skills to advance in their job and survive, raise a family, keep up their home, make friends, and pay their bills responsibly. In Get Together they have a lot of social interactions and with the Club system, that adds a new dynamic of following the rules to stay in, etc. :)
