There are some incredible things on the internet.
Watch this 81 year old grandma stun a crowd in Spain with her Tango stunt. She acts as a bystander watching a street dance act; telling others that she'd love to join in but she has a bad back. When the male dancer asks for a volunteer to dance with, she offers but is told that she is too old.
They begin to dance a slow tango. THEN... she goes wild! This woman is awesome and it just goes to show that you should never judge a book by its cover!
Enjoy and have a fabulous day!
