I've carried the same wallet with me for the last six years. This Coach leather wallet has been in my back pocket nearly everyday since it was given to my as a gift. It's been through vacations, bike rides, long road-trips, and God knows how many accidental rinse cycles. Recently I was browsing a shopping outlet and found the exact same wallet. It was then, when I was holding the new wallet side-by-side against the old wallet, that I realized how beat up the old one was.
I purchased it and when I got home, I moved the contents of the old one into the new one. But it felt odd; a bit too unfamiliar; like new shoes that hurt your feet. After a day, I picked the old one out of the trash, and put the new one in a drawer. Maybe one day it'll get used, but not today.
