What good are wings without the courage to fly ?

Last Friday it was pink shirt day, we all wore pink .we have to were pink because we need to
speak up that is why we wear pink. We need to support the people that don't have the courage to speak up.  

For pink shirt day our teacher said that we had to paint 4 pink  feathers per classmate. we had different shades of pink feathers.  Later our teacher cut the pink feathers and put it in a angel shaped paper.  It had a sentence above it , What good are wings without the courage to fly.It might not make any sense ... it means you have a talent, but what good is it when you have no courage to us it.

Why do we need to stand up to bullies. I think if we all stand up, the world could change into a better place.
