The 2 moment was quickly followed by mental math. How much time and money would it cost to replace the 3 of that little wallet ? The credit cards , the driver's license , the cash , all lost to the bus. Two hours later , back at my house , I heard a knock on the door. My husband 4 it while I was on the phone in the dining room. "Does Jennifer live here ? " I heard a lady say. In my husband's hand was my wallet , with not a penny 5 .
