I can't listen to Butterfly Kisses by Bob Carlisle without crying.
My dad first listened to this song when I was born and the moment he heard it, he thought of me as his first born baby girl. My dad passed away when I was 9 years old and I had never known about this song until that night when my mom played it and we cried in the truck. >_< I absolutely hate country or gospel music, but this is a personal fav of mine merely for memories and sentimental.
It isn't really a sad song, but whenever I feel the need and miss my dad, I play it and cry. ;-;
