she wasn't the only passenger

Watch as she sings an impromptu song as she walks around the train, but just before she exits the trains she sees someone sitting in a seat.

Do you think she was embarrassed? I'd say, YES! But then again, she seems to have a good persoanlity and sense of humor, so therefore maybe she wasn't so shame.

As for me, I'd have hid under a seat if it were me in her shoes. No doubt.

I sing that bad!!
