Sorry if it’s a little long I tried to make it short also excuse my English if there is any error

Okay so my school was hosting a event . My roommate was going with 2 of her friends. So, on the day of the event I didn’t feel like going but my other friend Amira convinced me. So Amira and I decided to go with my roommate and her friends . Amira is friends with the other 2 friends . I know the other 2 they came over for dinner once and I got to know them. So we all decided to carpool together. At the end of the event we all walk back to the car. And the girl driving the car said “ where do you guys want to go eat” I automatically assumed she was talking about everyone in the car but then the conversation turned into a 3 day between the driver , passenger , and my roommate. I was talking to Amira and I heard their plans of wanting to get chicken wings. So I thought that is where we were going to go.

I noticed we were getting closer to home. And come to realize they were dropping us off. They dropped off Amira and then went to drop me off MY ROOMATE said “ leave the door open i might be a little late” because she’s didn’t bring a key I brought the door key with us.

I said okay and then left. But I was really shocked at what happen. I idk what to think usually when things like this happen I doubt my mind and think I am over exaggerating and is not a big deal. I think it is but I wanna hear your thoughts . Should I even bother confronting ?
