I am from a place where there's no train/subway or anything, but I was broke growing up so I did ride the city bus which is easy to use.
However, the first time I rode the subway in Boston was a terrifying, overwhelming and disorienting experience. Didn't help that it was rush hour and also everyone on the east coast just automatically fucking hates strangers or something so I had some trouble getting help to work the ticketing machine, one MBTA worker literally laughed at me. Once I was on the train there was nothing to hold on to because of was packed like sardines and I thought I was gonna fly into the people next to me.
Anyway my Midwestern ass wanted to avoid it after that. I buried that feeling and figured everything out for my next ride though (I discovered the MBTA app), but I think a lot of people take mass public transit for granted if you were blessed enough to have it all your life.
I at least tried unlike this lady though lmao
