Silence in Noise

I wrote about Silence last week in response to a class and worship service I attended.  

This week in Sunday school, the moderator told us about a concert she attended.  The music was VERY MUCH not to her taste. She said that she discovered as she sat there, trying to block out the music, that silence was something you could find even when there is noise around you.

I thought that was interesting. I'm going to give it a try this week. Is silence something we can find even when the world around us is noisy?

Is that the only way to find silence? Is it always noisy around us?

Am I too dependent on the lack of sound to find silence?
