Five times.
Five times have I lost my wallet.
You would think that by the third or even second time, I would have come up with a better way to keep my wallet with me. I didn't, not until the fifth time!
The first few times were not that big of a deal: leaving it at a friend's house, forgetting it in the car, and so on.
But the last two were the ones that really made me realize that I needed a way to keep my wallet with me.
The first of these two times was at the Texas State Fair, which is enormous and crowded. This was where I learned my first important wallet lesson. I didn't notice until just before we left that I had lost it; but we searched and searched and searched. Then, just before we left, my best friend suggested we check the lost and found (duh).
So in we went, and sure enough, to my incredible luck, there it was! An officer had found it and turned it in. Incredible luck, but I got my wallet back, with all the money still in it. The lesson I learned here was never wear basketball shorts and take a wallet. Those shallow, slippery pockets just beg the wallet to fall out.
The second of the two times was at a local mall. I was just eating ice cream and seeing a movie with a few friends, but somewhere along the way I lost my wallet. It wasn't until I got home that night that I noticed it was gone.
We went all the way back to mall and searched for a good 45 minutes trying to find my wallet. We searched all over where I walked, and we just couldn't find it.
But then, the next day, a very nice police officer showed up at the front door, holding a soaking wet wallet, with a soaking wet drivers license permit. I just couldn't believe it!
A little while later, I bought the be-all-end-all wallet solution: a chained wallet (Here's the actual wallet). Chains aren't just for show, you know.
So that's what works when it comes to wallets (and keeping track of them): a chain.
