A boy named Bobby is sharing an apartment with a girl named Julie.   Bobby's mother came to the apartment to visit, and while they were talking, she  kept looking at Julie in a suspicious way. Bobby took his mother out of the room,and said, "Mom, I know why you're looking at Julie that way, and just to let you know, we are just roommates. Nothing more!" When Bobby's  mother left, Julie came in the room and asked, "Bobby, have you seen the silver  gravy ladle?" "No," Bobby replied. "Well, ever since your mother was here, it's been missing," Julie remarked. "Okay, I'll ask her about it in my next letter," Bobby said. So in his next letter to his mother,  he writes, "Mom, I'm not saying you did take the silver gravy ladle, and I'm not saying you didn't take the silver gravy ladle, but ever since you were here, it's been gone. Love, Son." A few days later, Bobby recieved a letter  from his mother which said, "Son, I'm not saying you are sleeping with Julie, and I'm not saying you are not sleeping with Julie, but if she was sleeping in  her own bed, she would have found the silver gravy ladle long ago. Love, Mom."
