Lyric discussion by transparent_human 

I took a more simple and obvious approach to this one. I think it's basically a song written for his son. Mostly from this line,

Just when you think you’re done The war can never be won I’ll be there to pick you up And dust you off And bring you home And make you feel loved

Basically just a heads up for him like "Yea, the world sucks...be careful."
