I normally don’t ride busses (particularly at night), but I have been to some big football games in Atlanta, New Orleans, Tampa, etc and when it’s a game and many/most leaving the game are taking public transportation, it feels a little safer when you are going with the crowd from the game. I’ve ridden the Marta in Atlanta to/from the Falcons game before and ridden it at another time and it was a very different experience when you were with tons of other fans vs just a random time on a random day.
I don’t really understand leaving her boyfriend without going to the police first, but if she had the option somehow to hop on a bus with other fans leaving the area and felt it was her only option to get home, I guess I could understand it in this scenario.
