Mr. Denning wasn’t feeling that great. He just wanted to lie down. He went into his room and shut the door. The room started swimming, and the last thing he remembered before he passed out was that he had to get to the bed. While Mr. Denning lay unconscious in his room, his wife and daughter were in the living room. His daughter was visiting and had brought her dog and he began barking furiously. He normally wasn’t particularly fond of Mr. Denning and stayed away from him during their regular visit.
