she wasn't the only passenger on the train.

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!!
