Bus Pass Misfortunes

This semester started impossible for me to keep track of my bus pass. It seemed like once a week it would disappear. Luckily it would show up again a few hours later sometimes the next day. It got annoying that I couldn't keep track of it. One afternoon I went to use the bus and of course it was missing again. I searched in all its normal spots but no luck. i sat and thought though when I last used it and where it could be. I had remember busing to a friends house and putting it in my backpack while I was there.
I tore everything out of my backpack and looked in the pages of everything. Nothing. A week or so went by and still no bus pass. I didn't want to buy a new one it was almost the same price I originally bought it for. I was out of ideas searched my room went to lost and found. It was no where to be found.
One night I decided to write thank you note to gifts I had received while here at BYU, I had kept the letters I had received in my backpack. I pulled them out to get the addresses one I was holding upside down. Out fell the bus pass. I was so upset I had never checked there, but I guess there is more good that comes out when you write thank you notes.
