JOE JONAS'S DAY OF SILENCE

Yesterday, Joe Jonas participated in a day of silence to raise awareness for children in poverty..

Joe Jonas spent all day yesterday not talking. He took a vow of silence in order to raise awareness about the problems lots of children in poverty face.
The official statement from Free the Children is that it's to "Stand in solidarity with children who are silenced by poverty, disease, and exploitation."
So Joe spent all day doing exactly that. We hope he raised a lot of money and awareness!
Have you ever participated in a day of silence? What was it for?
