Does Anybody Even Care?

This is a question I often ask myself...I mean sometimes people will ask how I am but when I go on to explain, it's like they are not even there. I am an Online Marketing Consultant. For those (parents/grandparents/in-laws) that are not computer savvy, I feel I have a great way of breaking down what I do but the problem is that I don't think they really care. Sure, they ask but I don't think they care. When I ask them how they are doing...I care. I reiterate what they say, ask questions, and show genuine care and concern. Is it that I am dealing with people who lack intelligence or manners? Why do I care if they don't care? Not real sure but it irks the hell out of me...what about you?
