Before I rode to McDonalds the other day (I find it's a lot better than home for studying Mandarin (no TV or Computer to distract me)), I went and checked my mail. I put my Christmas card in a bag w/some of my other papers. The bag had a large hole, but the papers were larger, unfortunately the mail wasn't.
I'm nearly to McDonalds, when a lady flags me down from the Starbucks parking lot. She told me that I dropped my letter in the street a block back.
I went back, and found my card intact, and undamaged, then hurried back to Starbucks. Sure enough she was in there, so I bought the cup of coffee she had ordered.
