this song is a favorite it needs a little explaining however this song is about getting older and making more mature decisions. the first line has to do with when making a conscious decision to be more mature. the line please sign here sign away your youth. i like that i explain that ideals are the only true currency which mean that there are some things in life that you can not put a price on. the chorus needs alot of explaining the line to feel the wind across my face, reminds me of being a kid and riding my bike and as i grew older riding for my first time in a car with the window open then as you get older driving the car with the window open and the breeze coming in. next line the sliding doors that open to the morning of my youth, that means that old saying when one door opens one door closes and the mourning part is you almost miss apart of your life as you move to the next stage in life. next line as the sapphire wilts into the spring, this needs some explanation sapphire is the stone of my birthday month of september and so as the saphire wilts into the spring means as the years just keep flying by. next line this postcard image is chizled in my brain this means that that postcard image of a white house and picket fences 3 kids and a dog married the americana view of maturity is chizled in means that once you reach a certain age everyone starts asking you when your going to get married get a better job and the reason you mourn your youth is that the mystery escapes you the excitement in not knowing what will happen in the future instead of always trying to plan for the future. the message towards the end of the song is to stop looking back at your past and look forward to things that are coming up and that life can be a chore at times but things will work out.
