Where should I hide my new Prada shoes????

Every time I buy myself a new pair of shoes (my favorite are PRADA!!!!! :) I feel like Sherlock Holmes. You want to know why? Well, here is the proof: I buy the item-obviously very excited-, put it into my car, depending on the time of the day if my husband is home or at work, the bags end up on the passenger seat or in the trunk- and bring it home. Then I have to look around to see that none of my neighbor's sees me, since I live on a street where you can not even change your lipstick color without the whole neighborhood talking about it for a whole week, and bring it into the house. You think the worst is done? Well, no, it actually starts: the question comes up where to hide the boxes without my husband (and recently also my two daughters noticing them). Under thebed, under the closet, inside the closet... You name it. I think during that time I become the most creative hiding-place-finder.
I usually give every pair of shoe 2 weeks time before wearing them "publicly" in front of my family and stack the box on top of all the others. The best is to wear them a couple of times without my family being around, so in case my husband asks the soles are worn a little. This way I can always say with the most innocent face:" These shoes new??? No, I have had them a long time."
I just wonder if he really believes me, or if he wants me to believe that he believes it while the box stack ins growing and growing...
