"Silence is golden" is a phrase I wrote many many times over today. There were about four pages worth of 'Silence' ideas and I ended on this one... It's another that I'm not entirely convinced by but to be honest, I'm not that convinced by anything I do at the minute, haha.
I wanted to convey the idea of tranquility. Originally I looked at 'silence' as something darker... but decided to go with my personal feelings on it... and look at 'silence' as a peaceful thing.
