WHAT YALL THINK?

My younger sister (20) has a new boyfriend.

Me and her don’t talk alot anymore barely at all . We out grew each other and we live different lives, she doesn’t need me to anything and vice versa.

I noticed today when I looked out my window waiting for my Uber food I saw a car in front of our home but not in the drive way. I was wondering if that was my Uber order , I went to check the camera and my order had already arrived. Then some minutes later the car pulled in the drive and and my sister got out. I find it weird that the guy and her sat across the road before he drove in the yard . Should I worried ?

My idea is that she told him not to go in the drive way at first because she knows we have a big camera pointing right at the driveway so if that’s the case she’s hiding her boyfriend. But why would my sister hide her boyfriend kinda odd idk . I just know she’s told My mother about her boyfriend so I don’t think she’d be hiding him from her. I guess she’s hiding him from me . That would be scary if she is because what’s the reason why lol
