The music in their relationship had with the passage of years had died a slow death. Now it was just silence. A deafening silence that could not be drowned by the mundanity that life had become. 
The silence was always there, even amidst the chaos that their children made, amidst the joys that Christmas brought, and between the birthdays and bills, between mortgages and marriages. The silence has become the third person in their relationship.

And one day, one of them had enough. She could no longer take in the silence, it was killing her. And she walked out. Walked out of the life she had painstakingly built.

Only for the search of music.
