If you have to repeat yourself and ask for feedback
No, you got this wrong.
OK, I edited my earlier post! Replaced "and" with "or". My bad!
It still seems to me that you want them to be interested enough to listen to what you have to say but you are missing the thought that you might not be interested enough to hear what they want to talk about.
Your mom is busy being "your mom"; she's interested in your well-being. Try giving her a detailed rundown on your life and times, I bet she won't miss a word and won't interrupt to offer to feed you!
The next time you want to talk to your dad try choosing a moment when he doesn't appear to be occupied and then bring up something that he has been doing; talk about his life and thoughts. So what if you have to first catch his attention! Maybe the guy is Thinking. Maybe he considers what you have to say to be "idle conversation" compared with what's going on in his mind.
Then again, and absolutely no offense intended, maybe these people are just limited in their outlook. I have cousins like that. Every time a guest walks past one of them the cousin will start with "Hello!" even if the guest just left them long enough to get a cup of coffee. They are lovely people, hospitable as all get-out, but they don't keep up with the modern world.
Take your relatives as they are. It might not be age. (Think back, how long have they been responding to people in this manner?)
