Dear Roger, My Dad is disrespectful to my mom almost every day, and it upsets me. He often tells her to stop talking because he's tired of hearing her talk. She's not nagging; she is just sharing her thoughts or talking about her day. He complains to her about her being overweight and questions her portion sizes while they are eating... and most people consider her a slim woman. We are all Christians and involved in church. Do you have any thoughts/advice that could help?
