She did and nobody cared!

The YouTube video description says her name is Angela Trimbur. She rocks out like no one is watching. In fact, hardly anyone in line even turns to look at her, even when she dances right up to them.

Trimbur wrote that she recorded herself dancing at the airport because she was feeling down over the holidays.

"I had a pretty lonely holiday... I didn't get to go home to see my fam this year & was really bummed, so I went to dance around people who got to do so on their way back from holiday vacay," the description says.
