Silence. It offers sobriety. It affords us the opportunity to think, meditate and contemplate.
On the other hand, when silence is used to hold a secret down, covered and swept under the carpet until the carpet starts bulging; then the wall around the secrecy starts to crack due to upward pressure from beneath. Things begin to fall apart as more cracks develop and gaps grow bigger.
The strings that hold the secrecy become more stressed and strained. The wall starts to cave in and out. The secret becomes a story telling itself.
No wonder there are gaps in memory when stories are not linear! Interesting.
