<human>: So a little background is necessary. My girlfriend is half Iranian, other half American. Let's call her Sara. Her dad is Iranian and her mom is from Virginia. Her mom and dad are very conservative. Her mom has even accused Sara of being too liberal.  They have family in town, Sara's cousin from Iran who now teaches in the US. Sara and I planned a New Year's Eve trip to the large city of our area, where we plan to get dinner, have a beer, and watch the ball drop. I received a text from Sara this morning informing me that her parents had invited themselves and her cousin on our date. Now this would bar most of the activities we have planned from occurring. We can't get a beer, I can't vape (I get it, I vape), we probably will not be able to go where we had plans to go. Now I respect her parents and what they have done to raise her. But it annoys me that they do this because Sara refuses to stand up to them all the time. She does live in their house, so she has to obey their rules, and I respect and understand that. This is just annoying though. She will not speak to them or her cousin to tell them we had a date planned and it honestly makes me a little upset.

Can you provide a brief overview of the text?
