The cat again!

Last night my mother-in-law and I where reading the news paper after dinner and she says to me. My cat is missing. He must have gotten outside. He hasn't been around for days and he hasn't eaten his food. I say, "the doors have not been open so I don't know how he could have gotten out." She said, "I don't know either but he is gone." She wasn't very upset about it so I went downstairs and there is the cat sitting on my father-in-laws lap. I went back up stairs and told her that the cat was down stairs. She just laughed and said, "OH".
