My mom and husband both do this to me, and it drives me crazy. I feel they don't think what I have to say is important. I'll be trying to discuss something with my husband, and he'll completely change the subject and start talking about something else. It's like, "Did you even hear me at all??" Or I'll be commenting on something mom has said, and she'll start on something completely different. Sometimes it's like I have to tell them 2 or 3 times because it doesn't even go through.
