Dear Abby: Is my husband trying to tell me something with his dramatically loud yawns?

Dear Abby: My husband yawns loudly over and over when we are watching TV in the evening. I have asked him to please not be so loud when he yawns, and he gets annoyed that I asked. He still yawns loudly many times a day. How do I get him to stop making a production of his yawning? — Blasted Out in Idaho
