Did I do the right thing ..?

Hello yahoo . Was out for a walk this afternokn and saw a car parked off to the side of the parking lot with 2 college-age people in back seat. No other cars there.Well I felt threatened by this because what if they are having s3x? I walked by and one was resting her head on the other . Felt nervous because what if nearby children see ... didn’t see any around but who know? I couldn’t see for sure if they were doing anything but called police just to be safe ... now I feel bad . Cops pulled up about 15mjn later and questioned them. Now i am worried and wanting to make sure I made right choice ... what would U do yahoo? #GodBless
