When I am happy, I like to sing. Loudly.
When I am sad or upset about something I like to sing even more. And even louder.
The song does not matter, as long as I know all the words and can sing along.
Music somehow helps bring happiness to my heart or peace to my inner turmoil - even more so when I can belt it out, unabashedly.
It's a good thing it's winter and my windows are closed.
