When my vet sends out letters, he addresses them to the pets. So, we got a letter in the mail yesterday addressed to Buster, saying it's almost time for his annual checkup. After I read it, I said, "Buster, you have some mail, you'd better come read it" and I held out the letter to him. He came over and sniffed at it for 5 or 6 seconds then walked off. My boyfriend just stared at him in disbelief!!
