After 17' is a song I wrote when my first daughter went to college, so that's kind of where I'm at in that part of my life. If you listen to that song and knew anything about me, you'd say, 'Oh yeah, he wrote that about his daughter,' but I try not to write them that they are so specific that they wouldn't apply to anybody that has a child.
The more Dad and Mom love each other, the more secure their children will feel.
