Why?

Day 4: A song that makes you sad 

I don't listen to this song much because I'm not a big fan of country music, but someone played this for me and it hurt my heart to hear. 

"Why" by Rascal Flatts

This is a song about suicide.  The lyrics are on the video, so I won't write them out below.  Isn't it sad?

Since I lost a friend to suicide four years ago, a broken piece of my heart is touched every time I hear the lyrics to this song.

What song makes you sad and why?
