A moral dilemma

I am in the process of updating my passport. The moral dilemma comes in that they want you to turn in your old passport...of which, I do not wish to do. My old passport is not expired yet, but my name is different and I suppose Sara Kate Ford version 1.0 no longer exists to the Government. "What's the problem?" you ask. The problem is in old passport: 1) has the visa's and stamps from my mission and my honeymoon, 2) has a dang good picture of me, which is hard to come by when you talk about passport photos. (Props to the folks at Shutterbug in T-town). So, I think, don't turn it in and say you lost it, etc. Well, the government's one step ahead of this sneaky mom. They make you sign an affidavit making you state that your passport is lost and the circumstances surrounding the said incident of losing the passport. You sign on the line next to a bold printed section stating that if this statement is false, it is perjury, and you will be so charged. Stop right there! Perjury?!?! Come on...I'm just sentimental. As I was falling asleep last night, I pondered over my plan of action. Do I lie? Commit perjury, in the eyes of Uncle Sam? Weiner me believes that I will likely just make copies of my passport and beg the lady at the passport office to see if I could possibly get my passport returned once they have "invalidated" it. Ugh. What to do, what to do? I don't think that they would ever know that I was lying. But my luck is that some loser would somehow steal my old passport and try to use it.
