Boyfriend and His Family

So I’m staying home alone while my parents are on a cruise and my boyfriend and his family are staying over at my house for the first time. I’m 15 and my boyfriend is 17. I also live in a farmhouse in the country and I’m at least 15 minutes from any town or city. I’m not really sure what to do when they come, I’ve only been dating my boyfriend for 3 months and I only met his family twice. Also I want to spend time with my boyfriend alone and I need some ideas on how to do that without seeming distant from his parents.

His parents are amazing and I really like them, I don’t want to give them the impression that I don’t. I also don’t want to seem boring when I’m around them.

What all should I do? I need help!!
